It helps with anti-censorship, not anonymity per se (afaict). The
idea is that many hosts have more than one address, and nearly all can
listen on multiple ports. Actually using this ability would allow a
bridge to actually accept connections at all its addresses (in the
first case) and help defeat naive port-blocking approaches (in the
second).
It's not exactly cutting edge stuff, but every little bit can help here.
