Well, it is conceivable that it could fail and have its motion limited in one direction but not the other. In that case, inverting the aircraft could force the stabilizer against the remaining limit, restoring some control. It's even conceivable that a combination of flap position and engine power could move the stabilizer against the limit and keep it there for a while, which is apparently what happened on the Alaska Air flight for a short time.
