I would certainly believe the intent is identical to every other "appeal" or option situation; batting out of order, using an illegal glove, catcher's obstruction, etc. If discovered 1) while at bat, fixed with no penalty, if discovered 2) after completing the at bat but before a next pitch to a succeeding batter, the option, or if discovered 3) after completing the at bat but after a next pitch to a succeeding batter, play stands.
