I'd be interested in that link if you can recall it.
I would guess, though, that the website was counting different forms of the 'same' word as distinct words - e.g., jump, jumped, jumping is three words rather than one word with several tenses. Obviously counting this way will multiply the same person's vocabulary several times vs the alternate way.
