Gordo realizes he needs to get out of here asap. Amon turned out a little too scary for his old ass to deal with all alone.
He wanted to get the hell out of here, but he couldn't just leave his guys lying on the floor. Luckily for them, they started waking up while groaning in pain.
He helped them up while keeping his eyes on Amon the whole time to make sure he doesn't get surprised and attacked by Amon, but having seen how easily Amon dealt with his men, he has no confidence in surviving an attack from Amon. But it's still better to be prepared.
Once all his men were up and back on their feet, they looked at Amon, scared out of their wits, wondering what kind of monster he was. But after the beating they were handed, they did not want to test him again.
They all then quickly make their way out of his office, to the parking lot, and drive out of the school campus under the curious, watchful eyes of the students.
