Correct. The AF sensor continually takes more samples even while the motor is moving. You can tell because sometimes the motor overshoots and then you can see it come back.

Yup… but it’s not necessarily in the same state if you do it twice. It’s close, but not identical. Even if the image metadata claims the focus point is identical, the lens in all likelihood is not in the same state and will have some deviation in its intrinsics.
