A person of integrity (Sappurisa Sutta)

In the [Anguttara Nikaya 4.73](https://www.accesstoinsight.org/tipitaka/an/an04/an04.073.than.html) , the Buddha said that a "person of integrity" possesses these four qualities: - when asked, does not reveal the other person's bad points and when pressed, speaks of the other person's bad points not in full, with omissions. - when not asked, reveals the other person's good points and when pressed, speaks of the other person's good points in full, with no omissions. - when not asked, reveals his own bad points and when pressed, speaks of his own bad points in full, with no omissions. - when asked, does not reveal his own good points and when pressed, speaks of his good points not in full, with omissions. I have paraphrased here, but the above is basically my understanding of the sutta. My question is how this can be considered an honest answer, or how someone answering this way could be considered a "person of integrity". I am thinking about a job candidate that has given a reference. If the reference answers in the way a "person of integrity" should answer, they would omit vital negative information and would furthermore only reveal that negative information when pressed. I am having trouble understand how these "shifty" and "slippery" answers are those given by a person of integrity and would appreciate someone clarifying these points to me.
