No doubt it sounds like a sound method. I have a friend running it now, and its killing him haha! Brandon and I share a lot of the same thoughts. I am not a box squatter, I think people need to spend more time with a regular bar, and I think your raw strength needs to be high before you jump into gear.
When it is all said and done Brandon is one of the best lifters around. He knows his stuff, he trains the way he teaches, and is happy to help. Need more people like him in the sport.
