Can that really be true? Surely there must be instances where ANO rules conflict with the local flying rules? Does "...wherever they may be." really mean anywhere in the world?!
So in Vegas last year, I happily and legally flew down the strip at night in an N-reg, but I couldn't in a G-reg?! That's bizarre!
Not sure if it's true the other way around too (G in FAA land), but if you fly anything with a N on it outside the USA and there are conflicting regulations, the more limiting regulation is the one you have to go by...
