The latter, an active uncocking of the Left Wrist when its turned to the Plane in Downstroke. This is not to say that CF isnt employed it is, this is additive. I got this from this video right here on the world wide web.

I hit a lot of balls with just my right arm on the club. My left couldnt do anything on its own until the day I employed Lynns hammering with a left arm only swing. And blammo. I used to pull the left arm and it didnt work worth a hill of beans one armed. But actively uncocking #2 puts some sting on the thing one armed or two.

I had thought it to be a 10-20-E Wrist Throw. Release Trigger. But Homer doesnt mention the active uncocking that Lynn demonstrates in my 6th anyways. Otherwise it sure sounds like it.

The Left Wrist Throw Trigger (10-20-E) can be either Automatic or Non-Automatic ("active" in your terminology). This is true for both Sweep Releases (10-24-B/C) and Snap Releases (10-24-D/E). Study 7-24.

Non-Automatic Releases are triggered by deliberate mechanical manipulation. In other words, the player consciously ("actively") initiates the action. In contrast, the Automatic Releases are triggered by driving the Hands through the selected Release Point (10-24-0) -- normally via the Aiming Point procedure (6-E-2) -- as if there was to be no Release at all (10-24-E).

So, the difference between the two is that there is no "starting to hit" (6-H-0/B) when using an Automatic Release (Sweep or Snap).
