This is expected thing. All utils that expect "bind" flag are broken.
There is nothing like "bind" mountpoint (and kernel does not maintain
such information at all), all mountpoints are equal, there is nothing
like a primary (original) mountpoint.
You have to think about it as about hardlinks for files. The bind
operation creates just another path to the filesystem. That's all.
mount /dev/sda1 /A
mount --bind /A /B
umount /A
then /B is still valid (BTW, this is impossible to describe in
the traditional /etc/mtab where was always relation between
/A and /B).
