Yes. (Except I would have called it "colour".)
And to me this gets to the heart of it: I'm in actor stance when decisions are low- or no-stakes; but I move to author stance as soon as things start to really matter; isn't - for me - play that demonstrates a commitment to actor stance only.
Following on from what I've just posted in reply to
@TwoSix:
It's not just reasons to stay together, although those are often so thin that taking it seriously as actor stance rather than author stance with a pretty light veneer of retroactive motivation.
It's the players understanding the whole structure of "plot hook", "adventure", "quest giver", "main quest", "side quest", etc - stuff that is manifestly not part of the fiction itself and not part of the way any person in the fiction would think - and then declaring actions on that basis while also inventing reasons why their PCs would make those decisions.
