But this is a behavior change from RHEL5:
[root@svvadm01 tmp]# cat /etc/redhat-release
Red Hat Enterprise Linux Client release 5.4 (Tikanga)
[root@svvadm01 tmp]# mkdir foo
[root@svvadm01 tmp]# ls -lad foo
drwxr-xr-x 2 root root 4096 Mar 24 10:31 foo
[root@svvadm01 tmp]# chmod 2755 foo
[root@svvadm01 tmp]# ls -lad foo
drwxr-sr-x 2 root root 4096 Mar 24 10:31 foo
[root@svvadm01 tmp]# chmod 0755 foo
[root@svvadm01 tmp]# ls -lad foo
drwxr-xr-x 2 root root 4096 Mar 24 10:31 foo
And I don't know of a good reason for the behavior change.

Man pages says as much:
chmod preserves a directory's set-user-ID and set-group-ID bits
unless you explicitly specify other-
wise. You can set or clear the bits with symbolic modes like
u+s and g-s, and you can set (but not
clear) the bits with a numeric mode.

Subject: [rhelv6-list] found a chmod bug in rhel 6.0
I think I found a bug with chmod, but I could just be
misinformed...
It looks like the numerical permission syntax for setuid/setgid
can only be unset with the alphabetical syntax on directories.
755 permission set on at directory
# ls -lad at
drwxr-xr-x 2 root root 4096 Mar 24 11:35 at
add setgid
# chmod 2755 at
# ls -lad at
drwxr-sr-x 2 root root 4096 Mar 24 11:35 at
attempt to remove setgid
# chmod 0755 at
# ls -lad at
drwxr-sr-x 2 root root 4096 Mar 24 11:35 at
didnt work
another attempt to remove setgid
# chmod 755 at
# ls -lad at
drwxr-sr-x 2 root root 4096 Mar 24 11:35 at
also didn't work
and one more
# chmod g-s at
# ls -lad at
drwxr-xr-x 2 root root 4096 Mar 24 11:35 at
success
This doesn't appear to affect files only directories.
