OK, so you're not suggesting that shaving made it grow coarser and more bristly, but simply that it felt bristly because it had been cut. How long your face stays smooth after shaving does depend on the type of razor you use, as well as the sort of hair you're cutting. Quite clearly your sister saw some reason to shave her whole face. As you say, when she stopped shaving and let the hairs grow out they weren't coarsened by the shaving. If they are coarsened, it's hormnones that's caused it.

Ten really-coarse male type beard bristles are ample reason to shave and may indeed be virtually un-pluckable. Ten fine, non-horonally-driven hairs on the chin certainly aren't.

I agree that ten hairs are not that many compared to women who have a full moustache and beard. On the other hand, coarse hair on the chin is indicative of the start of beard growth in earnest. There are many potential indications of what is going on -- one of the simplest is that when a woman's ring fingers are longer than her index fingers she can expect male-type beard growth if there's even a little stimulation by testosterone.
In my case, I'd been shaving my moustache every day for 15 years before the beard growth started on my chin. I have high free-testosterone levels so shaving certainly makes better sense in my case. Your mileage may vary.
