I did the same exercise on my reproducer and got the following pstree output:

When is switch to vtty with systemd.debug-shell=1, here what I got :

# pstree
systemd-+-bash---pstree
        |-recovery-menu---network---systemctl---systemd-tty-ask
        |-systemd-journal
        ....

# ps
root 486 473 0 08:29 tty1 00:00:00 /bin/systemd-tty-ask-password-agent

# PID 473 being systemctl start dbus.socket :
root 473 466 0 08:29 tty1 00:00:00 systemctl start dbus.socket

# PID 466 being recovery-mode/options/network
root 466 283 0 08:29 tty1 00:00:00 /bin/sh /lib/recovery-mode/options/network
