On the Back of the First Curve -- Why?

This one always puzzled me. It's easier to continue with the first curve and write the circle inside the first curve, then continue to the second, but instead we change direction right away.

Did Gregg (or his team) ever explain why they put it on the back of the first rather than inside the first? I'll trust the system regardless, but it would be nice to know if there's a reason.
