No. Perform the steps in the order described. It doesn't matter what classes you use as long as one macro does (save BRD->class1, load class2->BRD) and the other goes (save BRD->class2, load class1->BRD). You will set up your performance bars after activating the "To Performance HUD" macro the first time. The first time you press it is just to save your BRD combat bars elsewhere. Immediately replace it with the "To Combat HUD" macro but do not press it again until you're done setting up your performance bars.
