No, it doesn't.  Remember: the unwind directives help the unwinder
form the frame-state of the _previous_ frame (caller).

BTW: I didn't mention that yesterday, but the function you posted also
saves/restores r4-r7. Since those are "preserved", unwind-directives
are also needed there (my apologies if this is obvious...).
