isn't there a movement to kinda divorce "women's love" works from yuri? I agree here that from this section it sounds like the author doesn't want to be bound to the genre conventions of "yuri" and just write a queer story.
Yeah, there's a big difference between Nettaigyo's "it's not yuri it's friendship" and saying "it's not yuri it's women's love."
Yuri is a pretty amorphous term, but as a genre in Japan it's generally gonna be referring to the sweet, fluffy, non-explicit schoolgirls crushing on schoolgirls style of stories. The kinda stories that might own up to it being love, but aren't ever gonna admit that hey, these two girls are gay and might date other girls in the future. Which is why Yuri is frequently not viewed as that socially disruptive for what seems to outsiders like obviously queer romance - the Japanese mainstream can interpret it as a safe exploration of female romantic feelings as practice for eventually entering adulthood and heterosexuality. A big reason why yuri titles so rarely have male characters at all - because if there were actually eligible boyfriends out there in the story universe than it would be way too queer for girls to be crushing on girls anyway.
So terms like women's love are used mostly by queer female writers who want to write stories that are explicitly queer without that layer of "j/k it's just close friendship bro" that yuri so often has. Saying it's not yuri in that context isn't a nettaigyo situation, it's basically the exact opposite, "it's not about close friendship it's about lesbians."
