	I've wondered if the original sample had been much larger at one
time, and embedded in some sort of "auto-restart" loop (say, for a kiosk
application). In that situation, one would perhaps want the "app = None"
somewhere near the start to "wipe out" the previous GUI, and the "if"
was as a guard  to prevent a second start-up [if there were some other
loop also in the code].
