Is that a cause or effect? How do we fix?
Shift and swing or shift then swing are both entirely about how a hitter uses or does not use their hands. If you learn to turn the barrel immediately your body will support that goal and shift on time. If you are using your body to turn the barrel you have to shift first to create the needed momentum to get the barrel around.
Learn to swing/turn the barrel with the hands instead of the body.

I don't believe in your statement. The body is more important then the hands.
Now if you said the body is slaved to the hands and that the body supports or reacts to the upperbody program. Then I agree. It's called end gaining. In that you think about the end result, the upperbdoy or the end of the kinetic chain, and you allow the body to support the end of the kinetic chain. Using the body with no emphasis of the end result can create as many problems as it solves. So I agree with your statement, although the body is still the the power to the most distal segments (the hands/arms).
What jumps out at me....Front toss...shifts & swings. Front toss & tee swings. Swings with her arms. Like to see DD use her hands to turn the barrel. Swings around her body and seems to maintain the 'hinge angle'. Would prefer to see more of swing out from her body and 'oily' wrists. Again JMHO.

Maybe I should have used some SENSE and not say anything.......common sense.
