I don't know how to describe it, but it's pretty much like old manual primes,
i.e. the front part of the lens (with hood) from the focus ring on moves out,
and the whole lens block moves as a single unit (you can see on the camera side
how the rear lens moves by about 0.5 mm), and you can see the gap behind the
hood increase by about 0.5mm.

PS: He also made a focus map, from looking at about 300 images,
at 3-4 meter focus distance, pretty much everything is in focus

Ok, I've changed the wording here.
