I guess this might just be emacs Info-mode bias on my part (and the bias of someone who generally lives inside old documentation like this instead whatever the newfangled stuff is like I guess), but this behavior is precisely what I expect.

The relation of 1.1.1 to 1.1 is about drilling down into detail if you want that, where you can still peruse through at the given upper level.
