I never saw that advice, was it from Google official?
In any case, no pages got really killed, the greatest variation is maybe 10%, ie - some pages lost 25%, some lost 35%, and it's seems to be more dependent on how far down the long tail they were drawing traffic than anything else. That may be why the short pages were hurt less, they had less content for long tail matching.
All I remember Google saying was to eliminate low quality content. The strongest and longest pages certainly weren't the lowest quality, even in our limited spectrum of super high quality to very high quality.
