Because the bottom left White group is not particularly thick, Kitani gets what looks like a reasonable trade. But I still wouldn't call it an attack--it fits more with the idea that if your own territory is very solid, you can invade without worrying so much about it being trashed as a result.
I agree that it's an invasion (and that's what I called it in the post.
) I see a deep invasion as one kind of attack that is enabled by claiming solid territory in the opening. Whether or not you can make a direct attack on an opponent's weak group is just as dependent on the opponent's style of play as one's own.
