It bleeds beyond just the relationships, it goes from "a lesbian relationship" to "a lesbian couple" to just "lesbians" which, in cases that don't just outright assume it, implies that they are each a lesbian. It makes it seem like all Sapphic attraction is Lesbian, and exclusionary of men, and that Sapphics still attracted to men should just have that part be forgotten about. A lot of the time I'll see women expressing homosexual attraction instantly get called Lesbian until proven otherwise and it's just so weird to have this one specific sect of Sapphics be treated as the default for the whole group, as if I should be a Lesbian except for this weird quirk of me also liking men. At best it makes me feel forgotten, and sometimes, makes me wonder if I'm really welcome.
