I'd say there was a slight downwind component on the initial approach. Look at how the first blowing snow occurs almost right under the disc, despite the aircraft's quite high groundspeed). If the aircraft was approaching into wind, the blowing snow would have been further behind as the downwash first touched the surface. This would explain why the pilot chose a shallow approach angle and kept his airspeed up for as long as possible.
To the left of the picture is another helicopter, running on the ground. To approach the pad into wind over it would have been unwise.
It appears that this was a well rehearsed scenario and the passengers were obviously well briefed.
