Release and Impact (assuming the Ball located prior to Low Point) are "swinging right". Follow-Through and Finish are "swinging left".
Per 1-L #13, the Club moves "down and out" to Low Point. Thereafter, per 1-L #15, it moves "up and in". In both instances, per 1-L #9, it is simply moving in a circle.
Fortunately, to accomplish the above, all you have to do is keep your Head Stationary and point the Clubshaft/Sweetspot/Lag Pressure at the Straight Plane Line (1-L #6, 2-0/B #3 and 2-N-0).
