It sounds to me that the polylock did back off first. If the rocker had jumped without the polylock backing off the polylock would have still been tight on the rocker stud and you wouldn't have been able to back it off by hand...to me the locking screw not moving and being able to unscrew the polylock by hand points to this conclusion....
