The difference you are talking about occurs on the B routes versus the C routes. If you side with the fae (B routes), then Lester will get a sapling for you, which will allow Maeve to appear in your room instead of just the gardens.
This does not happen if you decide on trying to create peace rather than picking a side (C routes), where you can still only visit Maeve in the gardens. So if Maeve is in your room, it seems like you might be on a B route this time around!
Also, thank you for pointing out that inconsistency <3 (Your English is great and that's totally the correct word!) Depending on C or B route, it should either say "the empty gardens" or "your empty room". Looks like it got mixed up in that scene, I'll make sure to fix that! :)
