"Wouldn't it be better for mdpi to use xhdpi because wouldn't you get better quality by just halving the xhdpi resolution?"
Nope, it wouldn't be better. If the images are the same, just scaled versions of one particular base-image, lpdi and mdpi devices scale *down *to the desired size, which means that you throw away information. If you would use a larger image (xhdpi instead of the hdpi version), you'd just throw away more information than when scaling down form a smaller image. Using the smaller (hdpi) image is better for memory usage, since you won't load the larger (xhdpi) image into memory.
