That is not what makes it so confusing to a young horse. Every bit exerts pressure on the opposite side of the mouth when direct reining, that is how a simple snaffle works and why it is so effective. What makes it so bad with a TT is that when you pick up on, lets say, the left rein, the joint in the mouth flexes and the bottom of the left shank moves straight out to the side while the top of the left purchase pokes the horse in the left side of the face. The bit also tightens against the right side of the mouth as well so in effect, with direct reining, the horse is getting cues to turn left and right at the same time. If you use it while neck reining, this is avoided but it can still be harsh when you pick up both reins to stop. That is why neck reining and light hands are so important to be able to get along with this bit.
