Not exactly: since this should be done by the C code, it can ask the
window-system, which is the "current window under the mouse pointer".
The result depends on Z ordering, but Emacs doesn't need to know that
Z ordering.

The GUI window that's under the mouse pointer (according to the
window-system).

If they're both obscured by a third window (which does not belong to
us), then I don't think it matters much either way.
