This is a tutor you met who is not very cultivated. A person's self-cultivation is reflected in his way of speaking, which makes people feel very comfortable. If you have an unpleasant experience during the exercise, you can change this coach, which is your freedom and you also spend money. So there's nothing wrong with it. You can spend more time practicing some movements, which can also reduce the pressure on the coach, feel the movements more attentively and feel what the coach says, so that you can do it correctly.
