That is correct. In fact, the original offending text in rfc2543bis-02 is
fixed in -03. It now reads:
The user agent client uses BYE to indicate to the server that it
wishes to release
the call leg.

Proxies don't care about call legs. They are transactional entities. P will
simply forward the request based on the Route headers that should be there
when it reaches the proxy.
