I'm not sure what you mean by "inherently complicated".

The fact remains that the notation is very very difficult to learn, at least in the current way it is presented.

It's a kind of catch-22: The only way to follow the examples on those pages, is by comparing them to another ordinal notation you're already familiar with. But if we already have such an ordinal notation, we don't need SAN in the first place.
