If you sum the hair removed from one lil guy you’ll get 1. If you sum the hair removed from all lil guys you’ll get the amount of lil guys.
But yeah, you’re right. I think they’re looking at the problem differently. We don’t care about how much hair it has at each step. It can’t gain hair from a hair cut.
The sum of all haircuts is 2.
1, surely?

Maybe it would make more sense if I said “Hairdos”?
