It's just a handful of expressions that are mildly misleading.
In other cultures, you have to get together with friends over dinner to discuss the hidden meaning of a single suspect word your boss had used that day.
High context cultures take a lot of mental effort.
A related thought however is whether such lists, for any given culture, tend to grow over time, like special cases in legacy software, until the overhead of working with complexity exceeds the cost of starting a new culture afresh..?

The quoted source is an anthropological work from 1959, a time when anthropology still wanted to be a natural science. These sort of generalizations do not go over well in contemporary cultural anthropology.
A friend in South Korea was running late to the office (I think it was Samsung?). He made it in by his start time and went into the office bathroom for a quick shave.
His direct superior happened to walk in. As the boss was washing his hands next to my friend, he said something like, "make sure you do a thorough job of shaving" (though obviously not as awkwardly).
Other Koreans who heard the story confirmed this probably meant: "I see what you're doing: get yourself in order this one time, and if I ever catch you shaving at work again you're toast".
(Note this was about 15 years ago, and I hear Samsung and most of the other Chaebol have mellowed out a great deal since then)
