In short, IMHO, they've cocked it up!
It's quite possible to mount two different (or even the same) disk
partitions on the same mountpoint. It would certainly be a valid thing
to do if the union flag were specified. Otherwise, I strongly suspect
that only the last disk mounted will be written to, but you could create
a file under /home and see what grows with df.
I suggest pointing ad0s1g at /home2 (which you'll have to create) then
umount /home twice, then mount /home and /home2. Or, instead of /home2
perhaps /usr/local, but you'd have to go via a temporary mountpoint and
copy existing /usr/local to it.
Finally (or do nothing but) complain!
I've seen worse. The last (Linux) colo we got, had 60+Gb for /var and
5Gb for /home - completely backwards!
