The tools (not only df(1)) have to be fixed to de-duplicate the list
of fileststems. It's standard behavior that the same filesystem could
be mounted on more places.
The 'bind' flag is another way how to achieve that the filesystem is
mounted on another place. Nothing other.
# mount /dev/sdb1 /mnt/A
# mount --bind /mnt/A /mnt/B
is the same thing as:
# mount /dev/sdb1 /mnt/A
# mount /dev/sdb1 /mnt/B
there is nothing like 'bind' state of the filesystem. The 'bind' info in
mtab was always broken by design.
