Just saw the video.
Great, as this is how kites are self landed most of the time:
Of course, in really heavy winds with smaller kites and open space, you need to do it differently, but most who have'nt learned to self land, are not using these small high wind kites, and those who are, have figured things out by then.
The good thing about the method is, that if it goes wrong, the kite just sits on its side, no harm done and you try again
Around here, most kites have a high Y anyways.
Very natural to show the method that ALL kites and bars can use, instead of brand specific methods, thumbs up
As said, in light wind this is the way everybody does it (here), also with a low Y
