Fix:
inode number will be the same, independently on subvolume actually used,
and the reported subvolid.
But the mount reference count differs depending on the bind mount source.
In the first case, I can run
umount /.snapshots
in the second, I will get EBUSY.
=> The "mount -a" problem can be reasonably fixed, but depending on the
algorithm, we could encounter unfixable problem during "umount -a".
