You're right :) I can confirm the same. Thanks. 

It was silly of me to not realize > would have special meaning in the shell but
I'm also not sure using a character that carries special meaning in the shell
is the best of ideas. ':' seemed to be less error prone. 

This is where things stand for me:

root@orca:~ # sysctl security.mac.do.rules='uid=1001>uid=0,gid=0'
security.mac.do.rules: uid=1001:uid=0,gid=0 -> uid=1001>uid=0,gid=0

0x1eef at orca.home.network [~] % mdo -u root ls
mdo: setcred(): Operation not permitted

0x1eef at orca.home.network [~] % id   
uid=1001(0x1eef) gid=1001(0x1eef)
groups=0(wheel),1001(0x1eef),1002(_sourcezap),1003(_portzap)
