My French friend's comment was more about what he thought about Kirov style than anything to do with the ballet. (The view, obviously not shared by everyone
Your comments about the difference between Odette and Odile are very interesting, I think. It could be to denote a difference in character -- nowadays, the ballerina tries to be as different as possible in the two roles, which rather destroys the point that it's two different women, with the second one imitating the first -- obviously much much more difficult to do.
It also, however, could be a difference in choreographers, if it is true that Ivanov choreographed the second act rather than Petipa. (Something that several scholars are at least a bit skeptical about.)
