My reading would be that on receipt of a 0-lifetime RA that only the
second paragraph would be executed (lifetime timeout).  However, all
hosts receiving the 0-lifetime RA would then have to recompute the
next-hop, which in /some/ cases may require sending a RS (which the
rogue RA node would presumably hear and re-answer).  (Of course I
haven't verified this against any implementation :)
