Since it's been shot atLeweb 2012 it's probably more of a demonstration than a stealth flight like they did in NY http://youtu.be/M9cSxEqKQ78

Regarding the law it's a bit more complicated, owning one isn't a problem (Parrot is selling his stuff without troubles), but as for using it, you need to: - have a direct visual on it - no flight above 50 meters

as for a fly by video: - Must be at least 15 Km between uav and closest airfield - only allowed above unpopulated zone - no flight above 50 meters
