In his Hitting Stroke, Annikan uses a
Double Shift Plane Angle Variation (10-7-C) -- a Shift from the
Elbow Plane to the
Turned Shoulder Plane and back again. From the Top, he uses its compatible
Delivery Path,
Top Arc and Angled Line (10-23-D) wherein his Hands drop vertically from the Turned Shoulder Plane to the Elbow Plane before beginning their Straight Line Drive toward the Ball. Check out the yellow dots defining the Delivery Path. Note the three vertical dots opposite the Right Shoulder and torso, and compare them against the backdrop of the frame of the mirror in the background and assure yourself that they do indeed lie in a straight line. This is the 'vertical drop' from the Turned Shoulder Plane to the Elbow Plane and aligns the Hands for their Straight Line Thrust toward the inside-aft quadrant of the Ball.
All this is 'proof positive' that the four Straight Line Delivery Paths are possible (courtesy of Downstroke Axis Tilt via Hip Slide). There are those who say that the Hands can move only in a Circle (Circle Path Delivery), a contention that would make the Straight Line Delivery Paths an impossibility and hence the catalogued Variations bogus.

If the Hands are a portion of the Lever Assembly and they do not move in a circle as your 'proof positive' demonstrates, haven't you negated 1-L-8 and 1-L-9?
1-L-8. No portion of the Lever Assembly can swing forward independently.
1-L-9. Regardless of how the Lever Assembly is driven, it moves in a circle.
