I am a physical education teacher and a strength coach. My opinion on this stance is that his knees are too far forward in front of his toes and this stance is really bad for the knees.

Bend the knees to the point that the knees are in line with the toes and then drop the butt back and sit. The width of the legs and how far a person can drop is pretty much determined by the flexibility of the hips. That has to be worked on but can improve.

Turning the toes out slightly aligns the knees with the hips and reduces torque when doing repeated squats. The heel toe thing helps line the belly button up with the outside corner and improves vision.
