This has been fixed a long time ago.

/dev/tty0 is the foreground console, so it changes identity whenever
you switch VT.

"systemd-analyze verify" ultimately just runs the service manager with
different parameters, and there was a bug once upon a time, where the
service manager would use /dev/tty0 as it does when running PID1, but
of course it should not when running on a console.

Maybe update to something less ancient, or ask your distro to backport
the fix.
