It’s not Clinton Anderson’s way of training. It just so happened that in the episode he was working with a uncooperative horse who needed this type of training solution. He has other training methods that are excellent to learn.
In my opinion, you have to show a horse who is boss, if you don’t then they might get it into their heads as they grow older that they can boss you around and buck and do whatever they want while you are riding them.
believe me, I’ve worked with some stubborn minded horses before buying my own, and they had the same thought in their heads.
Some would even kick out at me in the lunge pen withing a few inches from where I was standing. But they soon learned to stop that after I whipped them in the a**.
