For two RO mounts, you need two RW dirs and two aufs mounts.
For instance,
# mount -t aufs -o br:/rw1:/ro1 /aufs
# mount -t aufs -o br:/rw2:/ro2 /aufs/sub-aufs
As you wrote, aufs doesn't follow-down the sub-mounts in the branch
which is a "bind" behaviour instead of "rbind". It is a specification of
aufs.
