Here's a great post by galopin from another forum

It goes back to what Yoda often says, that the hands tend to go down to Impact the same way that they go up to the Top. In the backstroke, a Hitter slowly swivels from the takeaway to the Top; he goes back down the same way--a long, slow swivel from the Top to Impact. In contrast, a Swinger completes his backstroke swivel early in the backstroke, and in the downstoke, he quickly swivels from Release Point to Impact.
