I guess only Miller Puckette can provide an answer about the intention. It also depends what we consider human readable: Does it mean that some or many or most humans can read it? It's a custom plain text format[0] that is perhaps a little bit less readable that HTML. I have been reading and writing Pd patches in textual representation (and I'm human). Not sure if that's an answer to the question. I've seen a Scheme editor that does visual representation, slightly similar to Scratch, but can't remember the name of it. AsciiDots is both visual and textual (although it's not two different syntaxes).
