Interestingly enough this exact phrase resonated with my personal experience deeply. I always found these personality categorization quite lacking. The most obvious one was introversion/extroversion. I'm a pretty introverted person in larger groups of unfamiliar people, but very extroverted in small intimate groups. Similar, but less obvious, situations and contrasts exist for basically all ostensibly opposite personality traits. The extro/introverted one also seems quite common (think people saying "I'm reserved at first but open up..."). So that context matters seems very intuitive to me.
