They are correct, you need to USE each of the combos on the boss to get the achievement. Good news is due to the lack of information/notification about it, if you have already completed Gold mastery you can contact customer support and they will give it to you manually.

As for the red combo, it doesn't work without the mission regardless of if that is what it is or not. I'd like to see the 'legit source' of information about it. Since there is no way any regular player would have 'discovered' it by themselves, it would have to have been leaked.

In any case, for anybody else reading, it WONT work yet either way.
