As much as it pain me to say it, that's what I see as well. I think it's impossible to declaratively state whether or not he made a "football move", or whether he was falling forward due to contact.
All that being said, I believe it should have come down to the call on the field standing for a lack of indisputable evidence necessary to overturn. I really was a coin flip...had the game officials ruled it incomplete, there'd be no evidence to overturn that, either.
The original call should have stood.
