...the Ohio QB seems to be talking to all of the players on his team - like he's calling an audible.
Hall had his hands up, like something was wrong, and was looking at and walking to the sideline.
I think you can mix up your snap count, audible or fake audible, etc. So you can confuse people about WHEN the snap is taking place. But you can't begin interacting with the sideline and walking off the field like no play is going to happen and then go.
