Extencior action is IMO very well described and demonstrated in Yodas alignment video. Personally I got a lot out of that sequence alone.

Isn't extensor action all about making the right arm pull/push on the left arm so the left arm is straighter and has more width in the direction the left forearm thru the index finger is pointing - in a downward direction below the plane (at impact at least)... testing...
