I think the current consensus is that it was an attempt at a trick play. The Colts weren't meant to snap the ball, but rather try and make the Patriots commit a penalty (offside). Colts head coach looked furious that they snapped the ball instead and caused the turnover (which a few plays later became a touchdown for the Pats).
We'll probably know more in the post-game conference, but that's going to go down as one of the worst plays ever.
