It's easier on fill rate and shader math, as you have to only calculate half the pixels per frame. I'm sure that the retroprojection is much less computational intensive than doing it the usual way, that's why they use this trick. On the geometry side is the same, but geometry isn't expensive at all, unless you are using an insane tessellation factor.
Graphics are always a game of doing more with less, developers use all the techniques they can use to improve the perceived graphical quality, and this is one of many tricks we will see in the future.
