I think that there can be ball flight implications as you claim - if a golfer doesn't know where to position his ball (for a given position of the pivot stabilising point).
That's why each individual golfer needs to know where his low point is going to be on the ground - based on the position of his pivot stabilising point in space - and he should then position the ball accordingly.
Here is Aaron Baddeley's clubhead swingarc and point "X" shows where the low point of his clubhead swingarc is located. Knowing that fact, he can simply position his ball behind the low point to ensure a descending clubhead path at impact.
The blue line represents the braced/straightened left leg. The red line represents the braced spine (and the degree of secondary axis tilt) at impact. By keeping the pivot stabilising point stationary, and having a braced skeletal structure (spine and left leg), the low point of the clubhead swingarc should always be at the same point - point "x". That allows him to place his ball just behind the low point to consistently ensure optimum impact alignments.
