According to 10-15-B, "Delayed Hip Action is the only Variation that assures Clearing of the Right Hip in both directions".

Why should clearing of the right hip be more difficult with Standard Hip Action where the hips are even leading the shoulders on the backstroke? And shouldn't the right hip on the downstroke clear just as well with Standard Hip Action as with Delayed Hip Action since the hips lead the shoulders with both procedures?

In this reference to Delayed Hip Action (and, specifically, the pre-cleared right hip), Homer Kelley was referring primarily to Hitters using the Angle of Approach Procedure (2-J-3). This procedure automatically produces a steeper-than-normal Inclined Plane. Paradoxically, it also produces a more "inside" Clubhead Path.

He told our GSEM Class (January 1982) that unless he pre-cleared his right hip, his Hands would not "trust him" to turn away in Start Up. Instead, they would immediately go back outside the true (more 'inside') Angle of Approach required by this Hitting procedure. So, the only way to satisfy his Hands was to pre-clear the right hip. Then, in his own inimitable way, he told us that if our Hands didn't have that issue, then we might find the pre-clear useful, but not mandatory.

Swingers with their standard Planes and "Swing Back" Motion (as opposed to Hitters using the derived Angle of Approach Plane and their standard "Carry Back" Motion) have more leeway. Here again, the pre-cleared hip might prove useful, but not mandatory.
