Nice citation, but this play doesn't tell us what to do if he doesn't leave the designated spot?

Continue doing what you were doing, which was counting to 5.

Obviously, by stating that we call a violation for A1 leaving the spot, there is a time between the fumble and violation that we are not supposed to anything but continue counting.

A lot better question to advance the conversation would be, "can Team A call a time-out after the fumble?"
