Such overlapping was rejected until last summer.

aufs: allow a loopback-mounted branch
It is rejected to add a branch which is a loopback-mount in another
branch. For example,
- /au = /br0 + /br1 ... + /brN
- /brX/fs.img exists
loopback mount /brX/fs.img at /out/dirB,
append:/out/dirB
This commit allows such case.
I am afraid you are just using an old version.
