I understand it a bit more now after looking at the flickr discussion.

If i have this right, it seems photoshop clones the pixels to make them bigger, resulting in a bigger image, with the same quality (or almost the same)

kinda like this:

Original...

RGB
RGB
RGB

Enlarged...

RRGGBB
RRGGBB
RRGGBB

So its still the same image, just bigger. But it seems to work better with RAW instead of JPG.
