Sometimes, the "DO NOT MOVE" is there because there could be an amenity being delivered and the hotel doesn't want to play "chase the amenity" if a room move happens. Room assignments are subject to change right up until your checkin (an earlier check in has a room still dirty, but the FD will shuffle among same room types to accommodate), so perhaps they want to be sure that you get the exact room assigned.
