What is impressive about that movie ? To me it's quite the opposite.. it's not impressive at all (too dark, bad fps) and when I watch it there is something in it that causes head aches. It's very hard to watch.
Shooting while in motion leads to a very shaky video. Being able to shot that steady video while using iPhone on a bike counts as very impressive to me.
I think he's trying to say that it's hard to tell because of the effects and filters added to the video distract from the example of stabilized video. The additional edits are unappealing to some so it's hard to get a feel for how the footage looks.
