It was certainly interesting and, for the most part, correct. iOS 7 seems to be emulating a lot of properties a physical object would have, but I have a hard time believing that anyone would describe that as “skeuomorphic.”
Colloquially, we use skeuomorph in UI to describe an element of the UI that imitates a physical object in order to quickly identify its function (e.g., a picture of a notepad to identify an app that takes notes) or bring a familiarity to it (e.g., a page flipping animation in a reading app).
While I will grant you that the word has been tossed around quite liberally to describe some of Apple’s design choices, the crux of your post relies on a rather distorted definition of skeuomorphic design that demonstrates a lack of understanding of the word’s etymology.
