Therefore I can find no justification for a batter to strive for greater separation during the swing.

Hey
Mickey Mantle would be a great example of a hitter that didnt open his hips during his stride,but he had great seperation because he counter-rotated his shoulders far back. Barry Bonds lands with his front foot closed but still manages to open his hips as his heel lands-his front knee usually lands in the direction between 3rd and shortstop. The more seperation you have while keeping your feet-"striding parallel" -the better.
