I doubt that the insurance was told the 407 was going to do full-on aerobatics, in (apparent) breach of CARs, manufacturers specs, etc. And even if it was told, so what? If what he did was illegal, no matter how many times you tell some insurance idiot, who knows nothing about flying and cares even less, they ain't gonna pay when you break the 'plane! As far as I know, all insurance relies on what you're doing being legal, which is why you won't get paid if you wrap your car around a lamppost while you're drunk. It'll be interesting to hear what CAA have to say, if they actually care enough to say anything at all. Do I sound cynical? Surely not!
