I need to know why even if I never use BOTH again.
Now I have no confidence that when I switch it to RIGHT, I'll be drawing fuel from the Right.

I'm not trying to beat a dead horse here, but...that's an Andair valve, and it has precisely 2 inputs (assuming it's not a dual valve with the return lines and all that)...Left and Right. If you simply took it out, and replaced it with the *drop-in replacement* proper valve, you'd never have to a) worry about being on Both again, and b) know for a fact that when you're on Left, it's drawing from the left, and when you're on Right, it's drawing from the right. You don't even have to change the lines from the valve to the tank or from the valve forward to the engine. Just the valve body.
Plus, you'd now be using the *correct* style valve for a *low-wing airplane*.
Do this, then run the usual flow tests on each tank, plus whatever crazy attitude tests you want to try.
There's right, and then there's not right...and fuel systems are NOT the place to not do it right.
