Is the item circled in red (just above departing helipad) in screen shot below what you believe is that helicopter? At first I thought this was features on the ground. I can understand there may have been a lack of relative movement given they were on a collision course, but it doesn't seem to get larger in the few frames it is in view, and no sign of rotors but that may simply be due to the video frame rate. Or did you see something else? It sure puts the collision somewhat more into context.
If you watch this video at 25% speed you can seethe rotors spinning.
It appears the pillar would have blocked the pilots view for a substantial part of the other helicopter's climb.
