I'm assuming you mean you saw the clip on the net, since it wasn't aired on TV, but although you sound genuine, I have trouble believing you, since I don't think WWE ever released the clip, and that's the ONLY way people would've gotten it, unless someone snuck a fancam in, used it, and uploaded the clip to the net, the odds of which are quite slim.
Well, Smackdown is a taped show transmitted by satellite, and people can get the satellite feeds if they have the capabilities, so him seeing it is not very far fetched of a notion.
