Try this explanation:
Turn the barrel is a pronation/supination movement. The bat is fixed at a 90 degree angle to the forearm and the forearm rotates. The range of motion is more than 180 degrees.
Knob to ball is a radial/ulnar (wrist) deviation movement. The bat starts with the wrist in ulnar deviation and transitions to radial deviation. 40 degrees of ulnar deviation and 20 degrees of ulnar deviation = 65 degrees total ROM.
Any "transition" you're seeing in the Chas Pippett video is due to the fact that he maxed the range of movement for pronation/supination and radial deviation happened. He also extended his back arm and it passed up the front arm so the barrel turned out of the hitting zone.
Turn the barrel develops crazy bat speed early in the swing (the blur behind the batter) and adjustments can be made via extension/radial deviation. TTB helps a hitter get the bat under their hands results in better launch angles. It also feel effortless. Any rotation of the body is quickly translated to the rotation of the bat.
Wrist deviation swings are easy to teach but timing becomes an issue because the barrel is slow to the hitting zone so it must be started early and control is sacrificed. The bat reaches top speed at arm extension and then it quickly exits the hitting zone (dead pull hitter, no power to opposite field if able to hit there at all) It's also the favorite movement of folks that hit down on the ball (chopping wood) After wrist deviation ROM is spent, rolling the wrists is the next movement.
IMHO
