Crazy play

I am a little confused as to what mistake there is to "eat".

If in a different play, the batter advanced to first on ball three, would you just allow that batter to remain at first and then rule the next batter improperly finished the first batter's turn at bat?

I hope not. I hope you would tell the batter that he is not allowed to be at first after ball three.
