It looks like I have to eat my words re. how many iterative phase comparison/drives are performed in a PDAF operation according to this article by Roger Cicala of LensRental: to Roger, the PDAF system is so fast it CAN perform multiple cycles of phase comparison/drive commands in order to achieve perfect focus. Faster than I could see when looking thru the VF, anyway I'll have to take time to read the article a couple of times to digest it fully. Cheers!

You can see it better by slowing the process down via lower light conditions with the AF assist off.
