Earlier quoted context omitted.
It mostly is. But sitting on your soles does change the proportion of your feet. I (and I think most other people) can't do that because my lower leg is too long.
Do you have a cite for that? I know plenty of people of various heights who can sit on the soles of their feet, it just uses muscles that most westerners don't exercise. I'm also pretty skeptical that it would affect your height in any way to do it regularly.
