The form above _does_ move `point' unless that's inhibited by other
(usually text) properties.  If *scratch* is displayed in some window,
`point' moves as well but the visible effect is overridden by the fact
that `window-point' in any window showing *scratch* does not move (wrt
to the surrounding text).  So I suppose the behavior you report is a
behavior you observed with *scratch* displayed in some window while you
executed that form.
