Actually it seems to have changed in Linux 4.12 and the uptsream
documentation at
https://www.kernel.org/doc/Documentation/filesystems/overlayfs.txt now
also says this:

| In the special case of all overlay layers on the same underlying
| filesystem, all objects will report an st_dev from the overlay
| filesystem and st_ino from the underlying filesystem.  This will
| make the overlay mount more compliant with filesystem scanners and
| overlay objects will be distinguishable from the corresponding
| objects in the original filesystem.

That said this bug is still rather annoying and I would like to see
it fixed, so I created a pull request upstream:
https://github.com/systemd/systemd/pull/6656
