Winds of Chaos

Is anyone using the Group Advantage alternate rules from the Up In Arms resource book? Im trying to understand the Advantage Pool as described. Is it a static pool or does it reset every round. Advantage from the core rulebook only grows until you fail or take damage. So if a players uses their advantage it does not go away. But with group advantage, it seems like when the advantage is used, the points are lost.... Am I reading this correctly?

Right, using advantage points from the group reduces the pool by the amount used.
