From a compilation on YouTube. I can't see anything illegal about it, just that the snapper goofed and the officials bailed the team out instead of allowing the busted play.
The snap seems to me to proceed exactly as it would have, with the ball leaving the snapper's hand where the quarterback would've had his hands, except the quarterback's hands weren't there. I don't see any hitch in the delivery, nor a failure to release the ball at the end of the movement.
