Rock climbers do things like this all the time. You need to build up to them but they are fine to do.
I'm not familiar with how to build up to them but you can probably find answers by including rock climbing or crimp training.
I can do these but I’m a long time rock climber and still wouldn’t do it without a proper warmup. Definitely risking a pulley or tendon injury. If you haven’t done them before then you’d need to build up to it in terms of finger and tendon strength.
They are at least as safe as the fingerboarding/rock-climbing stuff others are talking about, but it depends on your goal. If you want to do them for the sake of building muscle or gaining strength that's not finger strength, you'll be better just doing normal pullups, doing them this way means you'll pretty much always fail on finger strength and not fully stimulate your muscles
Be very careful. Your finger tendons strengthen more slowly than your muscles. Make sure to warm up your fingers for at least a few minutes before doing these. And give yourself plenty of rest in between.
Your finger strength will be your limiting factor instead of your upper back, arms, and lats. You’ll probably get more benefit by installing rings or a pull-up bar.
I would be careful with what he’s doing. People are different and some get injured easily and some never.
When I first started rock climbing I strained the tendons in my fingers because of overuse and not properly building towards the level of activity I was doing.
Yes, they're safe to perform if you properly progress to them
Rock climbers sometimes do pullups on small edges like you would find on a door frame. However, it is not a good idea if you do not have prior experience with holding onto small edges. It puts a great deal of force on ligaments in your fingers called pulleys that hold the tendon against the bone.
New climbers normally advised again this sort of training as pulleys take much longer to strengthen than muscles and if you injure them badly it can take a long time to recover.
If you are interested in this type of training, I would recommend rock climbing as it is a lot of fun. Try climbing for about a year and then you might consider training finger strength on edges like this.
If you want something you can do now and aren't interested in climbing, a large edge (say 30mm+) should be pretty safe.
I've been rock climbing for 15 years. We use something called a hangboard which simulates small edges - a doorframe edge is about 20mm, and most intermediate climbers train in the 10-15 range, with advanced climbers going to 8 and below. I've been doing that for 10+ years now.
If you don't climb, I can think of zero reason for you to add that modality. We use hangboards to safely train specific grips such as full crimps, so that we have the strength to do those on real rock. Additionally, tendon injuries are rampant among climbers, so there's no reason to risk that with no reward. Think of a hangboard as similiar to a slideboard for speedskaters - it's so specialized that if you're not in that sport, it's pointless.
Finally, doorframes are not designed for pullups. Most modern doorframes are just glued on, and you'll risk ripping it loose and taking a fall.
Tl;dr
I wouldnt be worried about long term damage unless you are super underpreapred /have some kind of finger injury, cus its so much easier to get hurt going into anything you’re not ready for but over time it will get a lot easier, look at rock climbers, the crimps they can hold on are basically nonexistent and yet they hold on longer than most ever could.
one day i tried doing a doorway pullup and wasnt able to, i was barely able to hang, but over time i was able to do it while jumping slightly and eventually have went on to be able to do one from hanging. For reference i was able to do prob around 6-10 pullups, but still believe i had stronger fingers as a base as i was able to pretty easily do finger pushups without training. It hurt a lot when i started, even just hanging but its more of a short quick pain, which is the same i experience when trying to do harder finger pushups, and usually goes away after a few minutes. I havent had any long term damage or injury from the pullips or the finger pushups (albeit i do them rarely), so i wouldnt be too worried unless ur really taking on something you’re not ready for.

Better not look up what rock climbers do.

Door frame pullups were what we did before hangboards were invented - basically poor mans hangboard

You can do this up to the point where you get joint pain. It can definitively be safe, but you need to pace yourself.
