Looking at the onboard video, I'm thinking the relative positions of the two machines maybe keep the departing machine in the arriving pilot's blind spot behind the windscreen pillar pretty much most of the time. If he's not heard or missed a departure call from the other chopper, why would he be looking for one?
At least he'll be able to provide one side of the story.
