How would teaching sequence *guarantee* proper hand action? IMO, it won't. Educated, live-and-independent or simply just "good" hands (or as FFS pics demonstrated and RHC said, proper hand torquing and tight hand pivot point) are crucial, and WON'T come naturally to most hitters.
I know most instructors/coaches talk about working from the ground up, but when starting from scratch with a hitter I teach hands first. Show them how to work the barrel with the hands. Explain what a hand pivot point is (the old Tewks video of how turn-the-barrel-at-the-shoulder essentially *IS* the swing). Let them feel what an arm swing feels like and what it feels like to take the arms out of the equation (as active movers). Demonstrate how the hands are the ends of the whip (and the body's big muscles and movements are the engine, not the arms). THEN (and yes...this is the harder, more important part) build the platform and sequence on top of which the hands work and get optimized.
My two cents...

One of these hitters is applying torque to work the barrel. One of these hitters is not.
One of these hitters is applying pressure perpendicular to the bat handle. One is these hitters is not.

One of these hitters has pre contact extension and one does not.
I love red hots video, i work on the pivot point, with a bag, for easy quick feedback.
simple reverse chaining for a young player.

I have the full clip with sound. basicly what he is saying is get rid of the pre contact extension, and just turn the barrel.
i am finding that if you give the "knob to ball" TYPE instruction, or "direction" it helps the hitters.
What i have done is taken what tewks is demonstrating and added the "hand pivot point" for the "bag drill" with no "direction".
i add direction later if needed.
Mann, there are no frames of pre-contact extension in the above GIF comparison. Miggy's swing is shown up to the 'short-to position', thus it is too early to be seeing pre-contact extension in a good swing.
