Guido on CheckIO?

I don't understand the relevance of "Guido van Rossum, the author of Python, is one of our most famous player. He is writing some really wonderful code reviews for our player solutions." for this mission. Does it mean that Guido is/was active here on CheckIO? If so, I think his handle on this site should be added cause I certainly haven't been able to identify him, yet. In any case, this bit of information comes across as somewhat out of place.
