Subject: Compression: per filesystem, or per subvolume?

Currently using Ubuntu Natty, kernel 2.6.38-9-generic, I have these
mount points using btrs subvolumes

$ mount -t btrfs
/dev/sda2 on / type btrfs (rw,noatime,subvolid=256,compress-force=zlib)
/dev/sda2 on /home type btrfs (rw,noatime,subvolid=258,compress=lzo)

Yet dmesg seems to show only zlib compression enabled
$ dmesg | grep btrfs
[   11.097908] btrfs: force zlib compression

Is this by design, or a bug?
