bgathens, Jim is absolutely right that you don't have to be a hooker for the video to be valid. What Brian is teaching is basically a correct swing plane. My problem was as Yoda would say a "preverse idea of axis tilt" instead of my right shoulder(right handed golfer) going down the line, it would almost drop down and to the west, if I was facing north. This would result in me dropping the club way under plane, swing towards 1:00 flip the club and get a snap hook. If I didn't flip my hands, I would get a block.
I now go the range and place a cardboard box about 3 feet long(looks kind of funny) parallel to the ball. The ball is placed right in the middle of the box and the box is no more than an inch to the right of the ball, just enough room to let the clubhead strike the ball. It's impossible to come over the top or I'd hit the box. I have to strike the inside aft of the ball, but then follow through on plane, if I swing to 1:00, I would hit the box on the follow through. I would say the technique is somewhat similar to Vijay Singh's water bottle technique. It has really taught me the proper swing plane, and has forced me to quit dropping under plane. I'm getting a much better finish, getting over to my left side and a very consistent ball flight.
Hope that helps...
