YOu can tell their classification from a baseball swing?

The general mechanics of most polished baseball swings are the same -- you're supposed to stay on your back foot, I don't think it is just something a such-and-such personality type would do.

Granted, some batters might rotate shoulder to shoulder more, but many times that depends on how they've been trained. Some hitters may have a "curly-que" at the end of the swing, but usually it means the bat is too small or the batter is too fat. Most rotate their hips 90 degrees, the back foot is supported by the toe at 90 degrees with the leg. I don't think it has much to do with their personality. All swings have different wrist movement and different ways of traveling across the plate though.

I wonder if top hand release (of the bat) tells anything?
