Player A has Hera in the Ghost and she has a stress token. The opponent, B, has initiative in the game.
Hera's maneuver is revealed. It's a red maneuver.
Now both players want to set the dial to a different maneuver. B does this first, because he had initiative, both players figure. A revealed a red maneuver, satisfying the conditions on Hera's card. So consequently A chooses a new red maneuver after B. Since there is no new 'reveal maneuver' step, the Ghost can now execute the maneuver that A chose.
I don't think this was the intention of Hera's pilot ability. Maybe it needs a clarification?
