That's an ironic mistake playing with the idea of negation being additive instead of multiplicative that is enabled by the subtle redundancy encoded in no/any/some.

Makes me wonder if it might be a linguistic eddy echoing from the clash of Germanic and Latin-based French, where negation contracted with the word is also very common (no idea if n'est and friends had been a thing in French at the time that clash happened)
