You might like to try

  (with-selected-window (buffer-window other-buffer)
    (goto-char (point-min)))

instead.

Every window has its own `point' (to which you have access via
(set-)window-point and that is also influenced by
window-point-insertion-type).  When current-buffer is the buffer shown
by the selected-window, moving the buffer's point also moves the
window's point, but otherwise no.
