The motor getting power after the stop is reached is not the ridiculous part, it needs to be that way to make sure the mirror gets back against the stop. The crazy part is that the ring gear teeth are smaller than the tolerances that can be maintained with the way the gear is designed, especially since the fixture parts are cast pot metal and there really is no proper bearing surface for the pivot. It'll be more obvious when you take it apart.
