I once thought so as well but Stefan convinced me of the contrary, see
this comment in window.el.

                       ;; Actually, even if the window is really dedicated,
                       ;; the frame is still usable by splitting it.
                       ;; At least Emacs-22 allowed it, and it is desirable
                       ;; when displaying same-frame windows.

Think of 'split-window' as of creating a new window somewhere near the
one of its argument.  And note that you can always split a frame's root
window instead or make your dedicated window fixed size.
