Elmer, I have to correct myself. Barcelona has an exclusive L3 cache, not an inclusive one.

Therefore, if one of the cores experiences an L2 miss, it will have to snoop all the other cores along with the L3 cache. Let's not forget about probes (snoops) from the HyperTransport link, which once again has to search all L2 caches as well as the L3 cache.
