A vertical and angled plane are both FLAT as well, and per 1-L-5, "The clubshaft lies full length on a FLAT, tilted plane." (emphasis mine)
OK, how about "so that the leading arm and club can travel across a FLAT plane"? It's the same for "angled hinge", but not for "vertical hinge", where the clubhead move on a vertical plane with the clubface facing the target all the time.

"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.

It makes a world of difference whether you are referencing "CLUB" as in shaft or face...
Per 6-B-3-0, "With true Throw-Out Action (no manual Clubface manipulation), Centrifugal Force automatically aligns the Clubshaft and Clubface for Horizontal Hinging..."
To prove this to yourself, tie a clubhead to a piece of string and spin around.
When the string and clubface are aligned, note how the clubhead looks...you will be surprised.
Comp,
It made me a little dizzy, but it sure did look like HH!
With my irons i feel a definate "roll" to produce a horizontal hinge action.
With the driver i feel like my hands are just hanging on... does this mean that i'm likely angle hinging if i don't "feel the roll"?
On the Flatter Plane Angles, Angled Hinging approaches Horizontal Hinging. Hence your ability to produce Horizontal Hinging with the Feel of 'No Roll.'
On the Steeper Plane Angles, Angled Hinging approaches Vertical Hinging. Hence the necessity for a more pronounced 'Roll' Feel to produce the Horizontal Hinge Action.
