I think the Aristeia is something which is often used in science fiction works, which seem to an extent to borrow on a style of Greek storytelling. The posts before me got that right. Another famous Aristeia being that of Star Wars, which I'll try to describe the way I interpet it:
Arming scene
The rebels prepare to attack the imperial battlemoon, or death star, they converse and promise eachother to return and tell stories of their victory.
Brilliance of the hero
Obi-Wan Kenobi speaks briefly to Luke Skywalker at his take-off, stating the force is with him. This is the recognition of Skywalker being a hero, he is the one with the force on his side.
Exhortation of followers
The squadron leader talks his fellow pilots into engaging the battlemoon. He advices them to stay low and avoid heavy fire.
Initial exploit
Rebels pilots and Skywalker use the element of surprise and great skill to disarm surface weapons, destroy enemy fighters, then quickly enter the battlemoon's trench.
Setback
The first of the rebel pilots start get shot down. Equally important, the squadron leader misses his shot at the exhaust port.
Divine inspiration
Skywalker is told by the squadron leader that it is all up to him now. He is now responsible for saving his friends. Shortly after, the squadron leader is killed, this solidifying Skywalkers hero status as remaining combatant. Later, he uses the Force, the divine, to make his shot rather than a targeting computer.
Renewed exploits
The remaining three fighters enter the battlemoon's trench, to initiate an attack on the exhaust port.
Double simile
Although actually placing expectation and event opposite (no-one expects Han Solo to come to help out, instead he goes as far as entering the battle), Solo proves his heart is in the right place and acts selfless by risking his own life to help Skywalker. The double simile comes from that not only Darth Vader is defeated as a result of the friendship and loyalty between Skywalker and Solo, Vader's own underlings bug out lacking his persistance and trust in the force, resulting into his remaining wingman bumping into Vader's ship when the wingman pulls up in panic: the very lack of loyalty which Skywalker's friends DID have.
The kill
Skywalker fires the shot, by divine inspiration, using the force instead of technology.
Taunting the victim
Vader is the only surviving member on the imperial side. He has to suffer the humiliation of his defeat and whatever consequence follows from that. It is an indirect taunt, one by the event occured rather than by the victorer. One can however possibly perceive Solo's enthouciastic brag/comment as a taunt.
Back to WiH.
So for Noemi's Aristeia, the double simile may actually be the difference and thin line between trust or confidence, and overconfidence. The Hood acted overconfident and found itself leaving loopholes (for the AWACS, the attack, no contingency for keeping such an important factor as the Toutatis occupied), while Noemi and her team trusted on skill, clear-headed thinking and failure on the side of the opponent. If confidence is interpeted as trust, then trusting on eachother to cover one another was another factor and each did their component (AWACS, calling in reinforcements, good timing on the Toutatis' side) to achieve victory.
