It does sort of make sense. I've always fretted about what I understand is my "double-shift to the elbow plane" (a little like Sergio's old move). One of the best things I did was have Brian M look at a video of my swing. After he told me to not worry about the double-shift I got back to just "swinging" and not constantly fiddling with trying to eliminate that shift. My ball-strking has been really good the last few months and I don't spend all my practice time trying to eliminate what seems to be my natural motion. That equates to more short game time and I feel like I'm playing to my zero handicap again.
I still think there is more precision to be had in my swing, but it doesn't consume me like it used to.
My thinking would be that assuming one has a properly educated set of hands . . . may be a Plane Shift can be a good thing. If you know that you are gonna be "under" everytime, things would be a bit easier to predict. You could be more "under" sometimes but at least you know it's some degree of "under" EVERYTIME.
