The picture is great and many comments are right, if the guy is hot dogging then it''s just plain stupid.
The aircraft though is capable of this with the right handling and matching pilot skills. I personally would love to see more helos do this on the airshow circuit.
If this guy was a factory demonstration pilot then he very likely flew the aircraft well within her "envelope". There is a difference between hot-dogging when you are a legend in your own mind and flying an aircraft such as this within limitations.
Impressive maneuvres are not bad for the airframe when properly executed with an aviator skilled enough and knowledgeable enough to do them. What young aviators need to know when they see photos like this is the context of it all, this is not what you do with 350 hours in your logbook to impress your friends with your employers'' helo.
It may very well be something you do at the Paris airshow to sell the machine to perspective clients when you are the factory demo pilot with 10,000 hours in your logbook.
I have a photo I cannot link but I will post it in the foreing military section of the photos on this site. You will see an aviator from the British Army Air Corp putting his Lynx through her paces, very impressive and something you only do with the right machine, skills and circustances. I''ll title it, Going Ballistic Too, the file is titled "Lynx diving".
