Nope, it's not about the speed. It is about physical comfort and pain.
I'm 34, and have sadly discovered the reality of RSI over the past couple years (The author's final warning is appropriate). As a result, I've definitely modified keybindings specifically to avoid some recurring painful movements, and I think that's the reason the author discusses the topic, not speed of input.
