As noted, the depicted knot is the so-called "Flying Bowline",
which by my conception is not a *bowline* but something
else, with a (reverse) Crossing Knot base. Ashley shows a
similar knot as #1034, which can also be quickly tied, though
not with such video-propagating dazzle.
An issue with the shown knot is stability (frankly, I'm skeptical
that the razzle-dazzle "flying" tying will work on many ropes);
as Scott notes, a 2nd wrap of the end can be helpful.
