I liked the video a lot. But I gonna be an evil advocate here and say that while yes, I think it's very helpful, but it's helpful only if done correctly and horse can still stay connected and travel round even with lighter contact on rein. If one tries to go "long and low" on horse that doesn't know how to go on contact and use the hind end the "long and low" will become "cool, there are no reins lets just mess around however I wanna to".
