It did not contribute to a yes/no answer, which is good, because it is not answerable with "yes" or "no", and the article points that out and explains why. So I would disagree; it does contribute to answering the question, in the form of spelling out why it is unanswerable.
Compare:
"Have you stopped beating your wife yet?"
"I do not beat my wife."
The response contributes to the answer, even if it brings you no closer to "yes" or "no".
