He could have grabbed him a little. What's Jericho supposed to do, sell the move after Orton went flying by him, Gayda style?
That's the problem w/ his version of the move - he's only using 1 arm to hit the move, so, coupled w/ his jumping application, it's easy to mess up the move, esp. if the person taking the move doesn't see him coming. He really should work at getting it more DDP-like.
