Assets can be re-used if the scene takes place in an already visited locale. This chapter breaks away from our usual haunts, and that means all new locations to create, to light up, to bake HDRIs from, new outfits, etc. If the chapter after the upcoming one sees us back at home again, or back at the locales created in this chapter, we can reuse stuff.
Assets for people doing "special" interactions (
) with others (or themselves) don't benefit as much from this effect, as they're usually created for one scene. Although sometimes parts of poses can be reused when create a similar scene, or the action takes places in a locale that's already created, and that means there's a little bit of time saved.
So as to your specific question, assets are built for a specific purpose/scene, and sometimes they can be re-used partly or entirely, but it's not like you create a nice buffer of them for the purpose of saving you time down the road, and the story dictates if and what is needed foremost. It's not the story that gets adapted to get the most out of available assets. What that means for future chapter(s) remains to be seen.
You see I'm deliberately steering away from what might be spoilers, but I hope that's sort of an answer for you.
