One could look at it that way, but I also think he's more concerned about the sub's physical health. I read the article and don't agree/like some of his comments but generally he created the essay with the intention of enlightening overzealous tops/doms etc that can get carried away, in order to prevent future harm- and in that idea its good to know.

What I got from reading it, is that his point is to try to inflict the most amount of pain without permanantly damaging the girl's body- its just weaved in with his own personal views on some bdsm activities that he doesn't agree with.
