extend further straight out, you tend to
get a push behind the ball that works against you.
also when you work across the ball with the natural arc, the swing is smoother
and you can control net clearnce better in my experience.
Trying to brush up while extending results in lower acceleration that comes from the shoulder. If you brush across you are pulling your arm in by bending at the elbow and this generates much more acceleration.
