Because it's ambiguous. A partition might entirely contain a volume (a
filesystem), but in your case none of your partitions contain a
volume. They're members of md raid first, only once that's assembled
is there a logical block device, which happens to contain the volume,
and it is the volume you're mounting. All you have to do is check
fstab, partitions aren't assigned mount points, volumes are.

and I make my mdraid's PV's for lvm, and create LV's that are my
file
systems which I mount.  so thats one MORE level of indirection.

disks -> partition(s) -> mdraid devices -> PVs -> VG -> LV ->
file
system.   phew.
