Hello Dave,
thanks for your question.
Yeah I too, tried a large number and run into "recursion depth error".
So, sure this example doesn't demonstrate its full potential. It's stupid, but I couldn't find better without running the risk of confusing the reader.
A chief case of using mutual recursions is "search trees". Check here: https://en.wikipedia.org/wiki/Search_tree

Cheers,
