Yes, it can be seen as a box filter (with the size equal to the stride length) on the nearest-neighbor upscaled image. Basically if you imagine overlaying the new square grid over the old one and then each new pixel gets a weighted combination of the overlapping old pixel squares, weighted by the overlap areas. To my eyes it's more pleasant than Lanczos, which has too much ringing.
