Why was this version of the Stark vs Loki scene abandoned?

So recently I found this little animation that seems to be taken from either deleted scenes or some sort of pre-processing/concept work up of the scene before the Battle of New York of Stark vs Loki.

[Warning: Video is not on YouTube & takes a while to load, the clip is also 6 min long, I also can't guarantee that this is an official clip at all]

In this scene, it gives us a slight glimpse into what Loki does to manipulate his victims as it plays out and gives us a completely different dialogue path still leading upto Loki tossing Stark out of the window and obtaining his suit in free-fall.

By showing a more 'cerebral' side of Loki, other than his poking spree it also shows a more 'believable' (in a very loose sense of the word) way of Stark resisting the mind control by basically saying he has abused wayyyy too many substances.

First things first, is this even a real deleted clip?

If so, why was this angle of Loki seemingly abandoned/why was this scene removed for the poking?

After watching that video, my personal feeling is that it doesn't quite fit the rest of the movie. Loki isn't shown to be a master manipulator in the movie. Sure, he's got a bit of a silver tongue at times, but we never seem him do any direct mind control and we never see him truly convince someone to go against their nature without the spear. This scene basically betrays how Loki was set up in the rest of the movie. A sniveling kid given a new toy bent on world domination to prove to his father that he's better than him.
