Terminals on studs: Four and no more

Who pushed your button? There's a good chance the wire lugs make no contact with the stud. Current flows through the stack of lugs. The resistance between lug and stud is orders of magnitude greater than the resistance between lugs. There is no compressive force between lug and stud, that's why this resistance is high.

I don't need to read it again. I agree, the stud in the first case IS NOT DESIGNED to carry the current, but if you think there is no current flow through the stud, especially if there is any resistance in that tall stack of terminals, you're wrong.
