I agree the specific example is somewhat explicit, but the point being made is valid. Whether it's a subtle choice of words, lack of eye contact, or constant fidgeting. They can all have some additional meaning (or none!).
One example that I've heard is common is about reading body language that might indicate discomfort in talking about a subject, which might suggest under/mis-reporting of an issue.
