Because you did not use the -h flag.

Shutdown without the -h flag takes the machine
into single-user operation (run-level 1).


To do a COMPLETE shutdown (halt), do this

# shutdown -h now

It works, but shutdown sends signals(*) to still-running
user programs giving them the opportunity to exit
gracefully before being killed off with SIGQUIT which
causes immediate termination, which can cause corruption
of data-integrity within files if there is any sort of
file update which is only partially complete at the time
SIGQUIT is received.

(*) for details, do this:
$ man kill
