The hyphen hole is not a roulette, since it actually removed paper leaving a hole the shape of a hyphen. It is a perforation. So the roulette terminology is not applicable. Also, these were applied to sheets of stamps, not coils.

I understand the definitions, but to a novice US collector, on first inspection, they do look like slits from a roulette.
