Being 4th dan myself in karate I would not even show my students a kick performed this way except to show how NOT to do it. The supporting leg is going to be damaged if he does not turn the foot, he is likely to twist his knee out. The form of his kicking leg does not seem to me to be right. His foot should be turned down, which cannot be done unless he turns his supporting leg. Also he is leaning forward losing balance.
