It's basically an extension of the wing. When Boeing was developing the 764, they had considered a slight lengthening of the wing with a conventional winglet. Then the engineers discovered the raked wingtip was more beneficial. It performed the same aerodynamic skills and actually reduced the wingspan of the 764 to it's current dimention.

Another reason for the raked winglet is so that they can be parked in the same amount of space as earlier series 767, at least in terms of wingspan, I know that at some gates @ ATL, the tails of the 767-400s are nearly in the apron roads that run behind the gates.
