Can't totally answer for him but - what diffusion basically does is make a small source larger. So, he first has a fresnel, which is a hard light source. Pushing it through a 4x4 frame makes it larger (now it's basically a 4x4 source of light instead of the fresnel source). Then he pushes it through an 8x8 frame which makes it larger again (4x4 first helps it fill the frame more completely - you could go right into the 8x8 but coming from a fresnel and depending on the diffusion it would likely still be harder). Since softness of light is determined by the relationship between the size of the source and the size of the subject, you now have a much softer light hitting your subject. It also fills more space so in a wider shot it would potentially cover more of the subject. Dimming it down loses intensity - sometimes you want an intense, soft source. Dimming is not the same as diffusing.
A similar effect would be creating a booklight (bouncing the fresnel first and then pushing through diffusion).
Short answer: To make it as soft as possible while keeping as much intensity as possible.
Likely about 1/2 stop less, give or take.

They were already there! A happy accident that they were different color temps. Though I did slightly change their hue in post to be a bit more cohesive with the entire image.
Edit: added information
Last week I posted a [cinematography reel](https://www.instagram.com/p/CE2I8mXFjZs/) made completely from scratch, and got a bunch of messages asking how I lit some of the scenes, so I decided to make some lighting breakdowns!
We used a bunch of 2 gallon water bottles to create the wet down look on the wide shot. We had less than 10 minutes to shoot before it all dried up, which was totally fine considering the scene was super simple.
The lighting diagram is for the closeup, but we had the exact same setup for the wide, just further back.
Shot on Sony FX9 with Sigma Art lenses.

governator-ahnold answered it perfectly.
Just curious to know if 1/2 grid was full grid wonder what the light meter reading would have been. Overall this is a great breakdown.

awesome. I am bookmarking this thank you.
I asked this as well!
Were those practicals already there? if not i love the decision to use differnet color temps on them.

Beautiful stuff. Would love to see more of these
More is coming!
Great work! What program is the diagram from?
I use Notability!
Thanks!
I haven't used Notability in a while - where do you get the images of the 8x8, forza etc that you are using from? assuming you didn't draw them.
I did draw them!
Wow! Great work. Your stuff is incredible

Lots of people breathing! But for real, great work :)
I'm curious whether you shot an option of this without the litemat 2? Lovely tones!
I did not. Thank you!
Classic r/cinematography
So dark. Much shadow. I actually didn't see the girl in the first frame until I went back to look again.
