I think that 1-L #15 only applies after the low point. The low point is usually opposite the left shoulder, but when a golfer has as much secondary axis tilt as MA, then the low point may be ahead of his left shoulder. If his clubhead is still descending to its low point at impact, then 1-L #15 may not apply to MA's clubhead in that last photo. The clubhead may be just reaching its low point.
