My youngest daughter draws "correctly". She's very girly in any way, but when it comes to drawing a bow, her stance is as good if not better than her brothers'.
Look at this guy's stance. A photo model, obviously never held a bow in his hand. He's drawing to his upper chest too, facing the target...

Once you need to draw heavier weights and longer lengths, it becomes physically impossible to face the target, and youneed to position yourself sideways.
Something else that popped into my mind: if you draw very far (behind the ear or so), a mediterranean release might be pretty awkward, as the string could easily slap the ear. Much less, however, with an asian-style thumb release. To do very long draws with a mediterranean release, a draw to the shoulder socket is more logic, however. Which is already a bit closer to drawing to the chest. This is what ELB warbow archers often seem to do, whereas Manchu or Yumi archers tend to draw at or just below ear's height.
