Yes and as I noted already, 1. Look at his elbow position. 2. He didn't even have time to bring that punch into his centerline to launch it properly since the guy literally "walked" into the punch.
WC still has shoulder rotation, you cant move your fist forward without said rotation, that is basic biomechanics. The difference is that, your elbow is down and as you begin full extension, the punch launches from your centerline. In this case he doesn't even get half of that extension because the opponent was nice enough to dodge his face directly into the punches path as soon as it was launched.
Now, when chain punching, in the interest of speed, your elbows will not come back as far. The key principle is the elbow pointing down so that is more aligned with the fist (from a purely biomechanical point of view.) That's it. Even with jacking back the elbow, as long as elbow position and centerline theory are maintained it is a WC principle, it is simply not advantageous to chain punching, it doesn't have an affect on the acceleration of or mass behind the individual punch.
Every circumstance does not call for chain punching. As a matter of fact, imo some people chain punch when not necessary. Fighting period should be about efficiency and if you can accomplish a goal either by chain punching through defenses, or via a trap and a single punch, so long as it adheres to the basic principles noted above, it is WC. If you go to the AC forum you will actually see an ongoing debate between those of us who see WC as a conceptive art and those who feel there is a "right way" and a "wrong way" to WC.
