I completely agree with you, but your initial argument was that "Joe Infinity page ∞" wouldn't be indexed because Google cannot index every viable page on the internet. That is true, and Google will certainly set limits on what pages is crawls and what pages it indexes. However, in this instance the articles were crawled and they were indexed and they were relevant at one point in time. But google decided to remove them from SERPs for some reason or another (age, lack of traffic, etc).
