'Swinging Left' Diagram

Over at Brian Manzella's forum (http://www.brianmanzella.com/) there's a discussion about 'swinging left' when there's forward shaft lean. A poster with the handle of 'detonum' posted this diagram explaining it.

I still have not fully grasped the 'why's' and the 'how's' behind the 'swinging left' principle. I will say that I believe a golfer needs to get shaft lean first, with a FLW at impact and a Bent Right Wrist at impact before they start worrying about 'swinging left.'
