Inspired by bubbers. Winglet extends and re-directs the point of reintroduction of divergent airflows, making the recombination more gentle, hence less drag. It allows the pressure side of the wing to act for a bit longer. There is a reason it is swept, I am thinking it mimics the sweep of all high speed transport wing design; less frontal exposure for area action.
