I partially agree but I encourage you to view the "just a bottle" line again. There are two different variants. If you've agreed to spend the night with anyone else she says ". . . first come, first served" Which is a saucy line:
She can't have a first date with you that night if you already promised to spend the night with someone else, indeed. As we already know, her saying she would want to keep you is for that first date, which is what you get if you take her up on the offer. What am I supposedly missing there?
And for the record, something missing from the video, but if you choose the dialogue option "I've arranged some.. company, yes. It could be a long evening." then she actually does exactly what she says she will do. She shares the bottle with you on the spot by filling your glass, because she knows you have other plans for the night. Do you need more proof that there's no subtext here?

This is a reply to you asking for more than just the sharing of a bottle together. You are asking for sex. It's her stating she does not want more, she wants just a first date. It's evident here, and throughout the game, that she's just not that kind of girl (Lae'zel is, though). I explained that already in the post you replied to. Here's the quote:
