Leadership: Rex vs zVader

Starmaxn

What happens when a Rex team is attacked by a zVader team? Rex gives his team turn meter, zVader removes turn meter. When a sith/empire character attacks it has 50% chance to remove 20% turn meter, the other members of the Rex team gets turnmeter (15-7,5%) if it is a crit. But what happens in an AoE? If all characters gets turnmeter removed and all are critically hit the result is for all toons:
First lose 20% turn meter and then gain 4*7,5% turn meter or 4*15% turn meter, meaning that they actually gain 10% turn meter or 40% turn meter if they are clones?

Is this correct?
