"transient_for" doesn't mean "stack this window above this other
window". It means (quoting from the ICCCM) "this window is a pop-up on
behalf of the named window". Swapping two windows around so that
sometimes one of them is transient for the other and other times vice
versa makes no sense by this definition, so there's no telling what the
WM will do if you do that.
The EWMH has some other hints that can be used to control window
stacking, although matchbox doesn't support all of them.
But then, if the two windows aren't both full screen windows, then
you're violating the Sugar HIG anyway. And if they *are* both full
screen, then why do you need to play weird stacking tricks, rather than
just show()ing them in the correct order?
