But you previously wrote that it might have to do with logging in
twice as the same user; what made you change your mind?

Your first assumption was correct.  Each connection to the server
will get a new connection object, so logging in twice as admin will
link two connection objects to the same user object, for the duration
of the login+password sequence.

In user::login(), connection(previous_object()) will formally establish
the link with the connection object, as well as break the link with the
previous connection object, if there is any.  The function is defined
in kernel/lib/user.c.
