Off the top of my head, I would say
- a "session" saved on the server, is identified by a "session-id" (some kind of large 
alphanumeric string, unique)
- to allow a browser to re-connect to the same session during several interactions, this 
session-id is initially sent to the browser, contained in a cookie
- whenever the browser interacts with the same server/cluster, it resends this cookie, and

this is what allows the server to re-connect this browser to the saved session

- of course, if you switch browsers, the new browser does not have that cookie. So it does

not send it to the server/cluster, and it gets a new session, with a different session-id.

Or did I misunderstand your explanation of what happens ?
