If I want to send leftovers home with people I will either provide the to-go containers myself, or explicitly ask them in advance to bring them along. I think it's entirely plausible that LW comes from a family culture of people getting sent home with leftovers: in my family it's not necessarily a given, but it quite often happens after big family gatherings, especially if the hosts have laid on food to the tastes of their guests that is less to their own taste. Usually though we're (re)using cleaned takeaway boxes to pack up the leftovers so handing some off to departing guests is easy enough.
I could totally imagine some of my relatives throwing a party and adding "bring a reusable box to take away any leftovers, we don't want food waste here". It's the step to assuming one should do so without any explicit mention of the idea that seems a bit much. But maybe that's how LW's family does it.
