Though this article is likely dead I'll respond anyways. As the author notes, when cabin altitude reaches 13,500 ft, oxygen masks automatically deploy. This pretty much destroys the entire theory.
Even if there was a slow decompression to 13,500 ft cabin altitude, almost no one would be unconscious. Hypoxia begins to set in as early as 5000 ft, but oxygen isn't even required in aircraft until you spend more than 30 minutes about 12,500 ft. Above 15,000 ft the average time of useful consciousness is still 30+ minutes.
