ATR72 Propeller

Hi
Having spent many blissful lunch breaks watching ATR72’s pull onto stand and shut down I have always been curious as to why one propeller (I can’t remember if it’s the number 1 or 2 engine/turbine) slows down and then stops very abruptly, as if a brake has been applied, whilst the other propeller windmills to a leisurely stop. Does anybody know why? Does anybody care? I’m just curious.
My guess is, if it is number 1, that that is the side the pax disembark from and it is done for safety reasons, but how is it stopped?

Cheers
