When i saw the phrase "lesbian enough" I took it to mean a woman who has no sexual feelings for a man. There are many women who are bi and consider themselves lesbian, just as there are bi women who say they're straight. I'm also thinking of my gay friends who came out after marriages. More that the words themselves might not fully describe someone's desires or interests, or that the person suppressed different desires. I don't know. Maybe I'm not getting my point out. I do understand why the phrase bothers you. Language frequently doesn't have the words we need to fully articulate concepts.
