yes, in order to be efficient, a control surface needs to be in a good airflow, with propwash the air gets rammed down along the fuselage and into the control surfaces,making the surface more efficient. The problem is that the movement is turbulent and circular, so if you don't have a long tail surface it might affect lateral stability (and do what he mentions in the video, tending to turn, mainly because there's no trim on the 109/Buchon rudder).
So once again, Messerschmitt engineers got it right, and improved things with the tall rudder versions.
