Double first base, appealing

Actually, 8-2-M-2 has a shorter appeal window when double first bases are used:

Whenever a play is being made by an infielder on the batter-runner, the defense must use the white portion and the batter-runner the colored portion. The batter-runner is out when there is a play being being made a first base and the batter runner touches only the white portion, providing the defense appeals prior to the batter-runner returning to the base. Once the runner returns to the white, no appeal can be made.

So, are you saying that, if the batter-runner returns to first, the appeal window is closed, but if he goes to any other base, the window remains open?
