Also, I think the layback position depends on the technique you're taught as well. For instance, my coach taught me to push the hips forward. The effect of this is that the thigh is close to the skating leg. So, how does Sasha and Alissa get the free leg so high?
Oops, you are correct. The attitude position comes in an arc in the upper back .
Sasha and Alyssa more than likely pacticed a lot of attitude turns off skates. Check out the 'Rose Adagio' from the Sleeping Beauty to see attitude turns. Skating takes it further and adds a layback to it.
