I think this is a very good gif. In my opinion, a number of things are happening between frames 8 and 11. One is initial direction. The hitter's eyes are watching the ball and sending that information to the hands which are making fine adjustments to compensate for speed and location. If you look at the location of the barrel in relationship to Miggy's head at frame 11 in each swing, you can notice some very small differences. I believe this is because he is not only adjusting his body/torso slightly to the pitch location, but his hands are making those adjustments as well.
I don't think there is a whole lot of difference. In my head, the jury is still out on how much - if any - physical adjustment should happen before launch, during the reading of the pitch location. I see a whole lot of it in the flawed swings of young hitters, but it seems to disappear in the HL swings we use as examples.
