My reading of the section 12 paras you have referred to is that the auth
headers from all the 401/407 responses are returned to the UAC in one
401/407 response, not multiple of each.
Your posting seems to suggest that multiple of these are returned.

-02 bis, PDF version, page 86; see handling of 4xx,5xx responses.

Nope; the non-2xx response has to be forwarded to that the UAC (and state-
ful proxies) can clean up their INVITE transaction. Unless you want to get
Jonathan really mad, always remember:
Each transaction completes independent of others
