i'm not sure what the question is... but hitting the F1 button multiple times will only swap window1 and window2 once.

if your region1 is your main region with pip hotkey F1 and wow1 is associated with region1, whenever you hit F1 and wow1 is not in region1, then it will be brought back. a single swap from whichever region it is in with the wow currently in region1
