I am pretty sure it was planned like that, but it definitely came off as awkward on TV. I think the point was that either Slater didn't expect Miz to actually get the pin, or that he was intimidated by Miz after he pretty much dominated Gabriel, because at this point I think the WWE was assuming that everyone expects the Miz to have to cheat or at least struggle to win a match, and while it did succeed in making the Miz look dominate and gave him arguably his most decisive win yet, the whole thing just seemed off.
