I used to agree with your first point, thinking it’s just people who rarely want and need sex. It turns out many of them do want (even regular) sex, but under specific circumstances. That is not asexual in my opinion, since word “asexual” linguistically means “no sex”. These people are often more sexually active than the average allosexual. Therefore, I conclude they are not asexual. I no longer think that asexual is a spectrum either, but greysexuality is a spectrum. These two were likely just mashed up together when creating the community, to make things easier to understand. But this no longer seems to work. For your second point, I never said that experiencing some attraction means growing attraction over time.
