I wouldn't mind having a definitive answer to this question (Apple
guys?), because my UI design would need to be completely different
depending on this info:
Overlapping views work on Leopard, but do not work before that. The
documentation is out of date.
As far as my experiments show, overlapping views only work if you
are using core graphics based views.
If you are using NSOpenGLView based views (my test case was actually
a mix of opengl and coregraphics based views), then sibling clipping
does not work (but container clipping does).
Sorry; I should have mentioned there are some exceptions...most
notably things with isolated CoreAnimation layer backed view-trees,
and gl views.
Please do log bugs on any issues you discover. thanks!
