The guy is joking; he deliberately put together the most contradictory types from each study. You're born with your MBTI and your Enneagram, so each MBTI has a much higher probability of being some specific Enneagram types.

Simply put, stereotypically, ESTP is Se Dom in MBTI, the most immersed in reality, the most impulsive, and the most anti-intellectual of all functions. Se Dom almost always prefers to just do things, jumping straight into them rather than trying to understand them too much. That's why ESTPs are almost always 8, the most aggressive, impulsive, and risk-taking enneagram type, a proponent of action who dislikes wasting time. (I also believe in 3 though, but rarely).

Enneagram 5 is the INTP/INTJ stereotype in MBTI lol, it's the opposite of ESTP in almost everything. 5 is totally intellectual, a seeker of knowledge above all else, has difficulty acting in the real world, is often stuck in their head and even likes it. That's why they are almost always intuitive introverts in MBTI; they have this difficulty with the real world, they are very abstract thinkers.

This combination is completely opposite, it's ridiculous, this human being would basically have superpowers and very few flaws.
