What they're testing isn't the in game quality settings. It's the min and recommended system specs put out on the games product page. For only 2 pictures/tests it's probably the best way to show that the game is playable on the minimum specs at low settings and that the recommended specs can handle the max at playable fps. I agree they could've done a few more tests and released say the recommended system at low, medium, and the high presets to give people an idea of the differences the in game settings make but for a quick check in I think it's well done.
