This looks right to me. The one case that isn't explicitly mentioned in
your test plain is when the user moves the pointer into a window owned
by an insensitive widget. In that case, the *ideal* sequence of events
would be to treat things as if the effective pointer window moved directly
to the root window, but it's probably easier to allow some extra events
so, if you have window C within window B within Window A, and C's owner
is insensitive and the pointer moves directly from A to C (imagine that
C and B are the same size), you'd ideally want to send only a leave
on A with a detail of Ancestor, but the easier thing is likely:

 leave on A with detail inferior
 enter on B with detail virtual
 <real enter on C with detail ancestor not delivered>
 <synthetic leave on C with detail ancestor *not delivered*>
 leave on B with detail virtual
 leave on A with detail virtual
