What is wrong with the left arm sticking to the body after impact?

The left arm blasts off the chest which allows you to get to Homers Follow Through position, Both ARms Straight with the club approx at 45 degrees to the ground , both flying wedges maintained all while still tracing the straight line, base line and the left hand/ clubface held perpendicular to the plane associated with the Hinge Action selected.

6-B-4-0 THE FORTH POWER ACCUMULATOR The angle formed by the Left Arm and Left Shoulder forms the Forth Power Accumulator. It is not only an independent Power Accumulator, but its Triggering function as the Checkrein of the Right Elbow is also vastly important and it thus can be the Accumulator of the Accumulators – or Master Accumulator. Also see 2-M-4.1. In other words, if the Left Arm Doesn't move, then the Right Elbow Doesn't move.
As Accumulator #4 it is Pivot (Body) Power supplying the initial acceleration of the Downstroke to throw the Lever Assemblies toward Impact by the Thrust of the Shoulder Turn. See 7-13. Another major contribution to Impact Power is geometric – it is the first link in the Swing Radius power train between the Club and the Feet.
“Left Arm Power” in any form or amount can still be considered #4 Accumulator Action. Otherwise it actually substitutes for the Pivot to introduce the circular motion required to produce Centrifugal Force.
6-A-2 THE PRIMARY LEVER ASSEMBLY An additional structural feature is leverage. A dual system of Form III levers. A Form III lever has the Force – or Power – between the Weight and the Fulcrum (2-L).
Consider the Left Arm and the Clubshaft together as the Primary Lever Assembly. The Left Shoulder is the Fulcrum, the Secondary Lever Assembly – Cocked or not is the weight. This assembly is normally propelled by the Arms. That is, Accumulators and Pressure Points #1 and/or #4 as discussed under 6-B-1 and 6-B-4. Movement of this Assembly must comply with 1-L-7 to -11 and 2-F.
1_L2. The Clubshaft, which is part of the Primary Lever, will swing Forward independently if the Upper Arm is held against the Torso.
7. The Lever Assembly is driven by exerting pressure against it.
8. No proportion of the Lever Assembly can swing forward independently.
9. Regardless of how the Lever Assembly is driven, it moves in a circle.
10. The Lever Assembly must be driven through Impact by an On Plane force (moving toward the Plane Line).
11. Clubhead Force and Motion is On Plane at right angles to the Longitudinal Center of Gravity and varies with Speed, Mass and Swing Radius.

Therefore, once the low point is reached the Lever Assembly must continue in its circular motion to the Finish.

I swivel maybe 10% of the time!Shoulder location has implications here as well . . . . also hip action and knee action and head location. . . which leads to shoulder motion. But you are correct . . . swivel is a piece of left . . . just not all of it.
