Anyway, they alight the opposite side they are boarded from. So in order to save time when riding them walking all the other way to the shuttle helps somewhat.
They were designed decades ago from one of the world's leading modern architects. So now, we travelers are living inside art.
As for entry exit, the answer is only partially correct. When you are coming from the security area, you enter on one side and depart from the other. When you are coming back from an international flight to customs, you exit the SAME side that you came in. That's why you see the less experienced travelers going to the back and the more experienced travelers and flight crew gathering at the entry doors.
This sometimes causes problems when it is very crowded as people do not want to lose their spot near the entry doors because it can cause an additional wait at customs.
Happy flying!
