Yes, that's what it means.

Indeed, it appears the doc disagrees with the code.
I'm not sure when the problem appeared, but the `compilation-buffer' is
(current-buffer).  OTOH compilation-window is not
immediately available.  (get-buffer-window (curent-buffer) 0) will
usually return the right window, tho.
