Incorrect infield fly rule called

It is impossible for the infield fly rule, called or uncalled, to affect the actions of the batter-runner. Given that the rules tell us that it is the responsibility of the players to know the rules - BR has no reason at all to not run to first (or no excuse should he/she choose not to run when IFF was not really in effect).
