Following DBUS Documentation,
There is only 1 dbus session per user login.

So DBUS is designed to get only 1 dbus session per USER.
I understand that different way, that new session bus daemon is started
on each login (each login creates new session). Especially because it
says "in session".
Otherwise things get screwed up when you activate for example X11
application through dbus, it would end up in wrong display, because the
DISPLAY environment comes inherited from the session bus daemon...
As an example:
1) I login with user "jussi" from local console on DISPLAY=":0",
"dbus-daemon --session" gets started
2) I remotely login over ssh with user "jussi" from remote computer on
DISPLAY="localhost:11" and run an application
3) Application I run in (2) involves dbus activation on session bus for
another application
