Someone more knowledgable correct me here, But you can 'leverage' more or less of the existing 'bounce' in a wedge design by opening or closing the face to bring that curvy base of the club into play more or less. The 'angle' that defines bounce might be constant, but shape of the bottom of that club head brings it more or less into play by allowing the face angle to decide low point of the club during the swing. Open the face - that take the low point back further from the LE and the moved contact point will bring the LE up a bit. Close it, that LE is closer to earth. I think that's what he's talking about, the tightness of the LE to the pavement, not just the built in angle of the LE at the vertex.
So - you're right, a SW with 12 degrees bounce is 12 with an open face or a closed face. It's not like a wedge is built concave on the bottom with a knife edge. he notes that he kept the face square - on purpose to tone the bounce contribution down - it's not like he's trying to avoid taking an early divot or anything - he doesn't need or want to apply the feature on this type of lie.
I think when guys say they are using more or less bounce in a club, they aren't talking about the physical dimension, they are just talking about opening and closing the face to emphasize or de-emphasize the impact of the feature (to keep a club from snagging into the surface)
I'd say you are right that some bounce is in play no matter how he sets up, but his point was to keep the LE closer to pavement through to contact by minimizing bounce. Thus the more close face angle vs what he'd normally have from off of a path. (he admits it's more likely to hit path slightly early).
You have to admit, it's a perfect lie. Why drop when he has this shot in his bag? - clearly it was not a big deal at all to him.
I recall another guy taking drops until he stayed on the path. Then hit a great fairway wood to the green. he just wanted the better lie (in his mind).
I really enjoyed the lesson in that video.
Edit: HA - went back read page 4. mvmac did a much more succinct discussion of what I was trying to note. and also noted that face angle isn't the only way to de-emphasize the bounce, hand forward too.... and he actually knows this stuff while I'm just faking
