In theory you will average them when you downscale the rendering to your display (that why it is silly to match the custom resolution to your display resolution). But it is true that due to poor ps2 resolution and high standard display resolution, the resolving part is barely done. However I don't know if it mandatory to resolve at same resolution. I need to do additional research.That a good point.
Except this resolving part, upscaling and ssaa are mathematically the same. Instead to store the value as pixels you store them as fragment. Both values are a color in memory. From a GPU pov the memory layout is different. And gpu is able to compress samples (due to the different layout). Honestly those stuffs are minor details of hw implementation.
