As I'm now an "aviation expert" according to the Daily Hate I better respond to this. The skin on the other side is indeed folded inwards however look closer; the ends of the torn skin are folded outwards. The inner section has a heavy window. When the tail section hit the ground the heavy window bent the skin back in. The torn end, bending outwards, still remains in its original bent position.
Ask me anything. I'm now an official expert. In everything.
