No, it didn't work that way without the patch: when you
mouse-set-point (mouse-1-click) in CVS emacs, the region deactivates
anyway, which _is_ normal behaviour in X11 applications come to think
of it (mouse-1-drag highlight some text in firefox, mouse-1-click
somewhere else...).   The insertion of deactivate-mark into
mouse-set-point makes the region deactivate immediately before the
point move rather than immediately afterward.  That didn't  matter
before (because nothing was trying to propagate out the active region
when the point moved), with select-active-regions the order of
move-point/deactivate-mark vs. deactivate-mark/move-point during
mouse-set-point is significant.

Guess should next trace exactly where in the call stack the region
deactivation is occurring in unpatched emacs.
