Yes, you are exactly correct...this experiment is simply an experiment to see if the engine is going lean, or low on air & fuel and is momentarily "strangled" due to that lack of air. With your background...which probably included the trials and tribulations of emissionizing automotive carburetors, you are probably well aware of why they all had "dashpots" to allow the throttle to close the last little bit slowly and uniformly. The experiment will give us a clue of a cause for the stalls....but more than likely, this would not be the "proper" fix.
