Incorrect.  Sessions don't know anything about logins; it's just data to 
them.  And the session ID needs to be unique for each visitor, whether 
or not they are logged in.

Can you imagine, for instance, a shopping cart where multiple people 
share the same session id - and therefore cart?  Many sites don't 
require any information until it's time to check out.
