For example: if you're in good shape you can run up a flight of stairs without any effort. But is getting in shape laziness? Not by any sane definition.
I'm sure you can think of a dozen other analogies, but they all illustrate the same thing: educating yourself, improving your tools, getting in shape are not laziness but the opposite.
And I think that's what original author meant. There is conflict between the definitions, and only the second definition indicates laziness.
