I made a similar argument, although I pointed out that the firearm still exhibited semi-automatic function since the trigger must be actuated by the finger for each firing operation. I also pointed out that some skilled shooters are able to bump fire with just their finger, no modification required. Some skilled shooters can fire a semi-auto just as fast as an automatic, so the rate of fire shouldn't have anything to do with changing the historical definition of what defines 'semi-automatic' vs. 'automatic' mechanical function.
