This is indeed correct. So you'll want to do something like this:
Code:
#showtooltip Aura Mastery
/cast !Concentration Aura
/cast Aura Mastery
With this, it'll show the icon and tooltip of Aura Mastery, but hitting it will put Concentration Aura on (and will leave it on if it's already up), and then cast Aura Mastery.
