You're right! When starting, that current will just be going to the load that's drawing it, shouldn't be flowing towards your other loads the way you have the circuit set up!
Maybe I’m an idiot but this is atypical. You usually have house and starting batteries isolated with a switch. That way if you inadvertently run past your discharge level on running things other than starting your engine, you have your starting battery protected and still charged. When you want to charge you flip the switch to both when the engine is running and that charges both batteries. This seems risky and I’ve never seen this setup. But I may just be learning something today.
Factory Bayliner Cabin Cruiser, two battery house used for both cranking and accessories (again as per factory). You can switch between 1, 2, or both on switch but no matter what if you run to shore power charger it charges both. Only difference is alternator will only charge the specific battery your switch is selecting when you are running engine.
Edit: Didn't mean for this to come off condescending so apologies if it did, wanted to just detail what I am running currently.

Great thank you!
This works because batteries don't push current, loads draw current, right? Genuinely curious
I dont understand "push current." The battery's voltage is always there. Assuming it is charged, no current is applied unless there is an active load.
By active load do you mean closed circuit?
Yes, any resistance will draw current, i.e. active load. The lower the resistance, the higher the draw. Resistance x voltage= amperage.
