It's my view, and I may be incorrect, that "hit vs. swing" doesn't start until release point. Both hits and swings are "pulled" until you get to your release point. Only from there will you continue to pull (drag) or hit (drive). I think this is why they both look similar...because they ARE similar until release.
For me, I intend to keep pulling for swinging or pushing for hitting.

"Sustain (Yang/陽) the lag (Yin/陰)" is "the unification of Ying and Yang" (陰陽合一).
The "LAW" creates the "effect", which is the "motion" or "feel", with the "cause", which is the "intent" or "command".
"Lag" is the secret of golf, passion is the secret of life.
Think as a golfer, execute like a robot.
Rotate, twist, spin, turn. Bend the shaft.
