Well, for one thing, the man is playing
Baat Jih Kim Yeung Mah "Character 8" Stance, not
Yi Jih/ "Character 2"...
For another, whether or not
Wing Chun can be distilled to the point where it is a "purely" short range system, with long range capability, that 'doesn't look like other styles", the fact remains there has been a history of blending and extrapolation evident, to such effect that there exist today in many
Wing Chun schools
at minimum some extra-systemic movement sections for cross-training purpose
(Gwa, Sou, Charp, etcetera longhands, for example)...
I would not go so far as to say that a curriculum comprised of 3 forms, a dummy, pole and knives could be viewed as "stripped down" by any measure, but rather that the
Wing Chun family is very large, spread out, and integrated with other systems, the result of good, long-standing productive relations...
Really, if it's like that overseas, then how the much more so at its place of origin, with so many more generations' contributions represented?
That being said, a couple of movements that seem to be different (after, of course, the standardly recognizable opening), include
Laan Tou/ "Overhead Blocking",
Bui Gim/ (Horizontal) Back Hammerfist,
Tit So Ba Gyuk/ "Iron Broom Kick", and a straightline rear-leg stepthrough, which is interesting, using the
Tiu Sau/ "Up-Flicking Hands" into a
Saat Geng Sau/ "Throat Cutting Hand"...
That footwork is not found in any of the (Yip Man) sets except the Butterfly Knives, which (short of actually asking the performer, or the man who designed the set) would tend to indicate a barehand application against a stick, or other blunt weapon (using the hands as "knives"), due to the actuality that a "straightline step-through" (attempt) from actual short bridge contact would, of course, expose your centerline...
The Big Sweep is always useful (and although what "looks like" a block in a set most usually isn't), so is being able to block your head (like if a second guy is simultaneously grabbing at your legs, a BIG SWING is coming, and so you can't
Jyun Mah/ Pivot, but you CAN "Block" to save your life!
Bui Gim is just an extra-heavy
Fak Sau/ Outward Chop, ok...
I don't see this
Fuk Fu Kyun set as being "complete" (as HG
Gung Ji Fuk Fu Kyun, for example), or even particularly essential, but probably just a few auxilliary concepts that the
Sifu felt worthwhile to put into an actual choreography, as "contingency" techniques (implied, but not necessarily found, as such, in other sets), encapsulated for future generations' ready usage...
Siu Lam Nam Kyun clearly represented!
Best,
Michael
PS:
Hap Ga Kyun Pok Yik Sau Faht clearly represented here as well...
