The squirrel test shot surely shows that Pentax have a sense of humor and pays attention to the PF!
As for the phrase you quoted I am also wondering what they mean by that. I can only think that since you gain one stop with the FF over the APS-C maybe by closing down the aperture to compensate the exposure you gain better IQ and resolution and in the peripheral areas that shows most...
Or on the other hand if you can shoot in FF mode with a DA lens (any crop designed lens that still is almost FF capable) you will get a wider picture that when cropped down to the APS-C size it will give a higher IQ image cause it will be coming out of the central part of the lens (not the whole lens that deteriorates toward the corners).
