Het zou mooi zijn als je nog wat meer context zou kunnen geven.
In eerste instantie denk ik dat het te maken heeft met politiek correct gedrag.

typo: politically

Political correctness (also politically correct, P.C. or PC) is a term used in various countries to describe real or perceived attempts to impose limits on language, terms, and viewpoints in public discussion in order to avoid potentially offensive terminology. While it usually refers to a linguistic phenomenon, it is sometimes extended to cover political ideology or public behavior.

In several English-speaking nations, the term often has a pejorative or ironic meaning—typically connoting an excessive attempt by social or political liberals to alter language and culture. It is also sometimes used to describe attempts to respect marginalized groups (e.g., the Canadian Oxford Dictionary (Oxford University Press Canada 2001) defines political correctness as "the avoidance of forms of expression or action that exclude, marginalize, or insult certain racial or cultural groups" ).

According to predominantly conservative critics of what they call the "political correctness movement," PC involves censorship and social engineering, and has influenced popular culture, such as music, film, literature, arts and advertising.

Liberal and progressive commentators, however, argue that the term "political correctness" was hijacked by United States conservatives around 1980 and redefined as a way to reframe the political scene in the United States. They say that there never was a "Political Correctness movement" in the United States, and that many who use the term are attempting to distract attention from substantive debates over discrimination and unequal treatment based on race, class, and gender (Messer-Davidow 1993, 1994; Schultz 1993; Lauter 1995; Scatamburlo 1998).

Following your note, I think that the sentence may mean that this person knows exactly what to say and do and when to say and do it, and equally importantly, what not to say or do. He will typically have good social skills and a good sense of proportion.
