It looks like that you have two problems.
1. Use "remount,del=/storage4"
The simple "remount,br=..." doesn't detach the existing branch. In
other words, when you want to detach the branch, /etc/fstab is
useless.
2. Install aufs2-util
Generally mount(8) shows /etc/mtab which is maintained by
mount(8). Your output from mount(8) is /etc/mtab actually, and it
doesn't look maintained correctly.
For the aufs entry, some helpers in aufs2-util maintain it.
I am afraid you didn't install aufs2-util. In other words, your
/etc/mtab (output of mount(8)) is broken.
