I think he means that the cotter pin and it's hole doesn't take up the full
width of the notches in the nut, therefore allowing one to get sort of
halfway between a notch, though how you ensure it's held there isn't clear.
 In that you can't ensure it's held half way between a notch.  Something you
can do with a peen nut.
