Just because something's not patentable doesn't mean you can't get a patent for it, it just means it will be difficult to defend. Microsoft attempts to patent everything they do, whether obvious, based on prior art, or directly copied (BlueJ).

In this case the patent application is probably for something very specific and not the whole general system described in the article. It's also probably not patentable if all prior art were made known to the patent examiner, but it will probably be granted.
