In other words; the primary lever assembly isn't properly balanced for an on plane motion powered by an on-plane linear force.

[Color and Bold emphasis by Yoda]

Nor is a hammer "properly balanced". But, if you hurl one end-over-end, it must rotate around its longitudinal center of gravity, i.e., its sweetspot. Not symmetrically like a Chinese throwing star, but in a funky sort of head-over-heels way.

And so it is with the "On Plane Motion" of the Golf Stroke. The Clubshaft and Left Arm must rotate about the Sweetspot. Unless you prevent that from happening (which most golfers do). We have a name for that . . .

Steering.

The First Snare (3-F-7-A).

The "On Plane Linear Force" (Centrifugal or Muscular Thrust via the Right Forearm) is applied "at right angles to the Longitudinal Center of Gravity" (1-L-11). The Force (Thrust) is indifferent to the configuration of the Primary Lever (In-Line or Out-of-Line given the Grip and the #3 Accumulator Angle). Except, of course, as that configuration ultimately determines the location of the Sweetspot.
