Just check the scripts.rpa yourself. It is basically open source. Search apron.
It appears the two scenes are identical, but they are two distinct scenes. Conversations are mostly the same, yes, and dev might just copy paste and modify, but you need to change the reference to different scenes.
This is not all. To make everything immersive, dev makes two distinct schedules for rae cooking, conversations to get rae into these clothes, etc. Dev puts in lots of works, enough to make a whole new scene (and actually this IS new scene), and yet to you the two scenes are identical. I agree they indeed looks similar, and that is my point about next to nothing.
