Again, the Left Arm is On Plane when the Left Arm Flying Wedge is On Plane. Not before (during Address and Start Up) and not after (during Release and Impact).
In other words, the Left Arm or Left Arm Flying Wedge should theoretically be Turned On Plane between the Startup Swivel and Release Swivel.

I looked at a few down-the-line photos of various pros and noticed that most time, their Left Palm (and hence the Left Arm) is rarely turned directly On Plane between the Startup and Release Swivels. But it's still Turned, just not exactly On Plane, as it theoretically should do.
