I did not try the patch so maybe I misunderstand it. But is not the
problem that (current-buffer) is not the same as (window-buffer)?

If so then perhaps using

  (save-selected-window
    (select-window outwin)
    (with-current-buffer (window-buffer)
      (goto-char (point-max)))

would do the expected thing?

But it looks strange to me. How does one know that this will change the
point in outwin? It would be much cleaner with something like a defmacro
`with-window-buffer' which would take a window as its first argument.
With that defmacro the code would be

  (with-window-buffer outwin
    (goto-char (point-max))
