Would this be another clue that Brian is hitting? More cross line hip action versus spinning the fly wheel?
I teach the Standard Fix (10-8-A) to both Hitters and Swingers. At Impact, the Left Wrist is Flat and the Right Wrist is Bent; the Weight is slightly left; and the Hips are "comparatively squared away," i.e., only slightly leading the square Shoulders.
