setuid not working on directories, or am I doing something wrong?

$ whoami
wmoran
$ mkdir test2
$ sudo chown daemon:daemon test2
$ sudo chmod 6777 test2
$ ls -lah | grep test2
drwsrwsrwx   2 daemon  daemon   512B Jul 25 07:40 test2
$ touch test2/testfile.empty
$ ls -lah test2
total 8
drwsrwsrwx   2 daemon  daemon   512B Jul 25 07:41 .
drwxr-xr-x  59 wmoran  wheel    6.0K Jul 25 07:40 ..
-rw-r--r--   1 wmoran  daemon     0B Jul 25 07:41 testfile.empty

Shouldn't testfile.empty show up as daemon:daemon? or am I
misunderstanding something about how setuid works?

This is on FreeBSD 7, but I observe the same thing on 6.3 and 6.2.
