When I X-step, my left foot crosses behind my right foot. It would seem very awkward to do it the other way.
A backhand throw starts with a neutral stance (throwing shoulder facing target line), then closes during the backswing (rotates 90 degrees away from target) then opens (rotates toward the target) in the forward swing.
If your plant (right) foot is crossing behind your left it will hinder any hip rotation as well as compromise balance.
I believe the x-step to be a very basic, easy to learn natural movement. If you are practicing it correctly you should have it down in a week or less. When I started in the 80's I had a shuffle approach. When I learned about the x-step in 1990 it took me only about an hour of practice to make the transition.
