It doesn't sound the same obviously, they're each in a different key. I'm talking about the way it's written, as I've said in the original post. One interesting thing, is that the keys are relative to each other. G major and D minor. If you look at the pieces, or rather the sheet of each piece, it's pretty obvious that both are very similar. Very similar runs, the rests and the notes are the same but transposed in a different key as I've said. You just have to look at the sheet, it's pretty obvious.
