Using this Skill

I still don't understand what that means for Control Marionette's name. I mean, with combat mastery you can normal attack (although you need a different icon to hotkey a usable form and the final attack of the combo is considered an alternate version of the skill), and ranged attack lets your normal attack with a bow. But what does this do? It's for sure not a normal attack, obviously. And as far as I know you don't need to do any character switching to use fighter skills, etc.
