See page 112 :
When the proxy is aggregating information from several
responses, choosing a To tag from among them is arbitrary, and
generating a new To tag may make debugging easier. This
happens, for instance, when combining 401 (Unauthorized) and
407 (Proxy Authentication Required) challenges, or combining
Contact values from unencrypted and unauthenticated 3xx
responses.
I had not remembered that mention. But I do believe that "combining
Contact values from unencrypted and unauthenticated 3xx
responses" is the only reference in RFC 3261 to the possibility of
combining 3xx responses.
