Don't take this the wrong way, but in my experience, people who feel they are morally obliged to "always tell the truth and nothing but the truth" have low social skills. Whereas the primary goal of the lying woman from the article is to make people feeling comfortable around her, by withholding the naked truth from them.

You exemplify that with the "nice to meet you" and "pretty good, how are you" examples. You don't want to act weird, so you lie.
