First question: Yes, although you may want to consider the wisdom of so many things moving in such a short stroke.

Second question: No, you are using extensor action per 6-B-1-D

Thanks Slinger!

When reading 6-B-1-D he says "...use #1 pressure point and pull on the left thumb..."

The #1 pp is to the side of, or rather behind the thumb. I can only see pushing being the action. What is meant when he said "pull"?
