"shutdown --help" on both F10 and F11 result in this data:

"<snip>
The system is brought down into maintenance (single-user) mode by
default, you can change this with either the -r or -h option which
specify a reboot or system halt respectively.  The -h option can be
further modified with -H or -P to specify whether to halt the system, or
to power it off afterwards.  The default is left up to the shutdown
scripts.
</snip>"

So it goes to run level 1 or "s" by default.
