Section 5 says:
If the received request did not contain a Max-Forwards header field, one MUST be created in any request generated in the UAC side, as described for proxies in Section 16.6, Step 3 of [RFC3261].
It should say:
If B2BUA creates a request as a result of processing a incoming response, Max-Forwards MUST be added in any request generated in the UAC side, as described for proxies in Section 16.6, Step 3 of [RFC3261].
Max-Forward is mandatory for Request as per RFC 3261. So this case is possible only on response processing.
The existing text is correct. The fact that Max-Forwards is required to be present in a request does not invalidate text that says what to do if it is not.
