In the example they gave, they had 9 errors. 1 was something that leads to browser incompatibility. (Trailing comma at the end of the array. IE doesn't implement the spec, Firefox does.) 1 was something that often points to logic errors. (Inconsistent indentation.) And the other 7 were someone's idea of correct style.
That said, I suspect that this lint tool will catch some issues where technically correct code can make http://code.google.com/closure/compiler/ unhappy. If you're using the Closure library, that's kind of the whole point.
