Pivot differences between Hitting and swinging?

[mb6606]

With a folding chair against your buttocks the swinger will push the chair back out of the way with the left buttock. The hitter will move away from the chair in a cross line in to out motion.
The hitter therefore should move the set up plane left if he doesn't want to go in to out cross line.
