It's a bad pressing, which are known to exist. So yeah, the songs are not supposed to be the same on each side. Foxtrot is notable for having their first and only true epic, "Supper's Ready" taking most of the second side, but on the other hand, it might be worth something as a collector's item. You could put it back on Ebay, but play up the fact that it's a rare misprint, and I'll bet someone will pay decent cash for it.
