It very well might.
Speaking from experience I worked for my dad in his firm a few summers during college/vacations doing some light accounting/computer/admin/gopher work and even though he was a demanding pain in the butt he'll say it was a blast when I was around as every time I did something well, it was incredibly gratifying to him and gave him (who was in his 50s at the time) and it game him a boost. He was always sad to see me go back to school for the fall and spring semesters.
I would assume when Stephen or Brian B do a good job with something he must just swell up with pride and that gives him that same "rush" so to speak.
