This seems unsurprising to me. Presumably the language he designed fits his way of thinking, and he uses it to express his thoughts. As long as you still understand it he succeeded in using it to communicate, and with some people that's a lot better than them not communicating at all because they have to use someone else's language. If someone comes up with an amazing construct in an invented language and gets any outside eyeballs on it that can understand it, someone will transcribe it into a more common notation anyways.
