Sexual orientation and sexual preference are not the same thing, though people argue where the line is. If you want to see a real shitstorm, see people arguing online if lesbians who sexually discriminate against transwomen are transphobic.

Probably because there isn't a line. Rich and poor aren't the same thing, either, but there isn't a line between them either.
Humans like clear binary categories (to the point of trying to force things into them) but reality often doesn't oblige by being neatly structured around them.
Also, if e.g. a straight person says they have experimented with the same sex, I take that as potential evidence that they only like a few members of the same sex, but (comparably) many more members of the opposite sex.
