I've never been to Dubai and I have never stood outside at that height, though I have filmed outside on the top of the CN Tower in Toronto.
That said I do not believe that the section of her holding the cards was shot in situ. You can see the background or sky change densities when they begin the pull back. The reason I am sceptical is that having shot lots of helicopter footage over the years I can not see how they could get such a motionless frame in such a close up at that height and with the winds. Even on a calm day and with little wind and a Wescam that is a hell of a shot for the pilot and operator. And yes I know they can shoot wider and push in and stabilize in post.
The rotor wash alone from the helicopter would make holding the cards impossible and the further back you go the longer on the lens you need to be.
I do believe that she is standing on the top for that part of the shot that speed ramps and pulls back.
