It's not obvious, I agree.  But I don't think it's very useful, except
in very specific and IMO quite rare situations.

If she doesn't care, she doesn't need to understand.  If she does,
there are enough hints in the doc string to suggest that reading the
doc string of next-window will explain those details.

Nothing wrong with that.  And possibly, an inquisitive enough reader
will discover that even earlier, perhaps much earlier.
