Some airports allow you to go to the ‘wrong’ terminal because there are services there. For example help desks, entertainment/relaxation areas for long layovers, children play areas, some have hotels in the airport, lounges, food/restaurants and more. Some airports also have the terminals connected after security, so you can go from one terminal to the other without having to go through security again. It really depends on the airport.

This. I've gone to the "wrong" terminal numerous time to access a specific Airport lounge that is clearly superior to the offerings in the "correct" terminal. Some Airports will actually try and actively discourage/forbid this.
