Simians didn't 'wave another KD really quick to avoid hostile' - the KD waved (HoH) had been served notice and the wave was planned. Sanc has even stated that they did not intend to hit Simians into hostile while they where still in fort so there was no hostile to dodge. Given the nature of the conflict the left hand knew what the right hand was doing, so it's a clear 2 vs 1 powerplay which included waving into a hostile.
