Usually, we hope that all of our accomplishments alert an employer to our general capabilities and compatibility with a position. Unfortunately, if the way we present those accomplishments makes us look qualified for a career in a different field (e.g. law), we have a problem.
If that's the case, we have to find a way to highlight what in our background makes us a good fit for the position to which we're applying. For example, if you clerked for a judge, you should emphasize your writing and research roles rather than the area of the law in which you gained experience.
Essentially, our resumes need to be a sales pitch as to why the employer should hire us. It should not simply be an autobiography that lets us bask in our own achievements. We always need to be sure to spin our experience to fit the position for which we're applying.
In other words, I think the article is telling us to lie...(j/k - I think).
