We put the session ID in the protocol so that you could support multiple simultanous PPP sessions from the same host over a single Ethernet (bridged ethernet over DSL in most cases) to the session concentrator platform.
Imagine one PPP session for Internet access; perhaps another for some corporate telework sort of thing. I don't know of anyone that actually has deployed services which have taken advantage of this, but we didn't want to preclude that sort of use.
