Thanks. Its funny because I used to hate Lleyton Hewitt earlier in his career. Didn't care for his personality (yelling c'mon in his opponent face, arguing with umpires, and of course incident with James Blake. However, I also watched him grow and mature into a much more professional and respectful player over the years and began to admire his grit and never give up attitude. He was able to overcome larger, stronger, and sometimes technically superior players with pure will and determination, to become a real inspiration. He also (IMO) had the most technically superior lob shot in tennis. You gotta respect that!

To be fair, that is the natural follow through and resent for that shot on the forehand side because all of your weight is on the right side (for a right handed player). I use that same follow through when hitting a forehand lob (learned it from watching Hewitt). Notice he doesn't do it at all for backhand lobs because his weight is more centered.

That's the follow through. I tend to hop as well when hitting the ball in general which may or may not be ideal. But in Hewitt's case, he is putting his entire body into that lob to gain as much top spin.
