The Biltmore lift is not a technique. It's a term that a particular surgeon is using to describe his or her facelifts. You will need to ask the surgeon exactly what it entails.
I am unacquainted with any procedure by that name but would agree with you that platysmal plication and transection of neck bands in addition to SMAS plication in the cheeks are extremely important components of a properly done facelift that will look natural and last a long time. Appropriate autologous fat grafting and elevation of the cheekpads are additional components of the facelift that I routinely perform and feel are important.
