It was explicitly requested by Al Viro to use "none" for some
VFS operations years ago (c4966ccb16868fa748009a826340fac9d1b1ce39,
0fae284a7a13d4d2dba7a908e0662a6d9c46f877).
I think it's correct, because FS type does not make any sense there
and it's waste of time to try to determine FS type for MS_BINS or
MS_PROPAGATION operations.

Seems like you're victim of the mtab file. My Fedora 19:
# mount --bind /home /mnt/test
# mount | grep /mnt/test
/dev/sda5 on /mnt/test type ext4 (rw,relatime,data=ordered)
