I think you are misinterpreting what they mean. When they say they, "require that it reach over 30 lpmm", I think they mean in the centre of the lens. One expects the centre to be far sharper than the edges but having the edges close to acceptable centre quality is surely the mark of a very good lens!

I'm not misinterpreting them at all. They slam lenses in several different reviews for being below the "usable level" at the edges. The "usable level" changes depending on which camera body they chose to do the test on, but they're always disappointed when a lens performs below it at the edges.
That being said - maybe this is just one of those lenses that benefits greatly from a little sharpening in post. a lens test with no sharpening whatsoever isn't exactly a real world evaluation. *shrug*
