All I can say is John Dee was in search for a universal language.  This is great input for a universal language using numbers.  And this may add evidence for John Dee as the author.

So were dozens of other scholars (including A. Kircher). Some even succeeded in developing new languages, including a correspondent and friend of Kircher.

The search for universal languages became widespread in the 15th to 17th centuries and beyond (with Esperanto as a contemporary example) and was in no way specific to John Dee. In fact, he spent much more time searching for angelic languages than he did trying to develop universal languages. He was hoping they might reveal truths about the universe that he couldn't find in books.
