I don't know if this behaviour is working as intended, it just seems weird to me:

I have an underground belt with copper wires on both lanes, on the exit tile there is an ending belt to the side with iron plates on both lanes. If there are no copper wires on the exit tile, iron plate tiles will be pushed onto it.

This is the logic for a normal belt intersection, but I thought the underground belts would behave a bit differently.

This is called the Underground belt trick, see here for more examples:

It is already known since February 2013 and has been deemed by the devs to be Not a bug.

Alright, thanks for the clarification
