Yes, this is what I also hold to be the most relevant thing about throttle management on engine-out approaches. "Set it and forget it"- you should know what power setting you need already. Little or no jockeying should be taking place on approach. In the case of a well-managed throttle, the worst yaw will come on rollout when the good engine is brought back and the strong rudder trim is pulling the other way. At that point you have the time and space to do it smoothly.
