What I mean is 1) putting the most important things first and 2) adding sufficient signposts to make the structure of the document clear without having to read everything. I think a strict ordering by importance, which would make a document a kind of simultaneous recursive elaboration of all its points, would be unreadable for a document that, like this one, also has an element of explanation. I think this takes the essence of the inverted pyramid, but if you want to take a definition that is stricter then I'm fine to concede it's not.
