Reason ... you get propwalk ahead and astern. When going ahead, the wash
does not push against the hull.


I don't think there is a "root" cause of prop walk. It's just a sum of
many factors, some of which even counteract eachother which is why you
can't be sure of the direction of prop walk just by which way the prop
turns.

G I disagree. My feeling is rotation in a water medium is the root
cause.

Um, yeah. That's kind of obvious. Not really an explanation of why
rotation in a water medium causes prop walk though. It's sort of the
same thing as saying the root cause of prop walk is a different amount
of force pushing the stern left vs. right. You'd be correct, but it
doesn't really tell you anything you don't already know.
