At least, these steps succeeded on my test machine.
$ mkdir -p dir1/dir2
$ rm -ir dir1
rm: descend into directory `dir1'? y
rm: remove directory `dir1/dir2'? y

An interesting thing is, a warning about UDBA was produced. Which means
that by removing dir2, the something about dir1 was changed unexpectedly
and aufs detects it (and produced a warning). But I am not sure this is
related to your problem.
Anyway it will be a good help for me to investigate the problem if you
post these info.
----------------------------------------
- /proc/mounts (instead of the output of mount(8))
- /sys/module/aufs/*
- /sys/fs/aufs/* (if you have them)
- /debug/aufs/* (if you have them)
- linux kernel version
if your kernel is not plain, for example modified by distributor,
the url where i can download its source is necessary too.
- aufs version which was printed at loading the module or booting the
system, instead of the date you downloaded.
- configuration (define/undefine CONFIG_AUFS_xxx)
- kernel configuration or /proc/config.gz (if you have it)
----------------------------------------
By the way, I have posted about some unusual behaviours of btrfs.

Again I begin thinking btrfs is not usable still as aufs branch.
