Taking a low res game and line doubling it tends to amplify the amount of aliasing that is perceived by the eye, making or rather placing under a microscope exactly how block-y the graphics actually are.
By leaving it at its native resolution and hopefully with the scanlines that come with that, you break up each line of visual data which results in an optical illusion of there seeming to be more to the picture than what is actually there. To put it in other words, it acts as a form of anti aliasing.
This is especially apparent with games with simpler graphics from say they NES, where as newer more detailed games tend to fare a better.

You have to think less about the actual dimensions that the resolution implies and more how that resolution ends up being displayed.

This is by no means a perfect example, as I'll fully admit that they're from different sources and the original photos were taken from different distances, but the assets themselves are still the same.
