My thoughts exactly. I've had 4 sets of the gaskets on my car and none of them looked like that. There are other gaskets like that in the rest of the exhaust and they aren't directional but they also aren't between aluminium and steel. If I was going to pick a direction I would go with the smooth side against the fragile aluminium surface.
