A question on the !Maul and !Rune Strike keys.

In my paladin macro:
/cast [mounted] !Crusader Aura
/cast [nomount] !Retribution Aura

The !Aura, will be cast once and never again, until the mounted/nomounted condition changes.
I can push the macro 10 times in succession, and it is only the one cast.

Does that mean, you want a single Maul or Rune Strike?
Or in the case of combat abilities, does it mean you will push it once and it won't turn off.
And then after having hit, another push will turn it on again?
