What documentation are you referring to?
Halt is documented to simply invoke shutdown, if run from
runlevels 1-5. But it is not shutdown's task to shut down the
machine. Halt is supposed to do that, but not until runlevel
0.
You are not supposed to run halt, reboot or poweroff directly.
Yes, it is "correct", if you use a newer version of sysvinit.
"Correctness" means halt and reboot notice what you are trying
to do, and remedies the situation by automatically calling
shutdown (with -h or -r).
See 'man halt' and 'man shutdown'.
I think it would be better if halt and reboot only printed a
warning that your should use shutdown instead.

This is the correct way to power off.

Well, don't put the -p in the halt script, then. :-)
