Actually from the start of the cockpit video you can see pilot is in a left turn and looking down and left before looking ahead and straightening up about 6 seconds before impact.
Just before he straightens up he is looking directly in front of the A pillar where the departing helo would roughly be, it's hard to tell from the video but his lips seem to move just after that, I think he makes a call.
I speculate that he did sight the departing aircraft, assumed he'd been sighted and that the departing helo would give way, continues with his descent and calls to confirm.
