Guys, the glitch is when Lesnar fallaway slammed Mark Henry off the cell at 12:35. You usually can't just use a move and then they'll be knocked off the cell from the edges, from the ceiling yes but not from the edge. Plus whatever Mark was doing, trying to figure out how to get back up afterwards.
Damn, I am not even mad, just disappointed at how dumb this is, the fallaway slam could be seen as a glitch but because it happened so smoothly and Mark Henry even rolled of the side it looks as if it is the games mechanics to do that, correct me if I am wrong but it looks that way to me.
