No it's not that it assigns a projection, it's that it ignores the projection and just operates on pure coordinates. So if you bring 2 things in that are different projections (ie a UTM layer and an unknown) then unless they are actually the same projection they won't line up at all. If you were to turn projection on the fly on, then the auto guess incorrect WGS84 would do way screwy stuff even if both layers were the same projection. So basically, load up your unknown layer. Then load a known reference layer. If it matches you have a winner, if it doesn't drop it and try a different reference layer (different projection), and so on till you find the match.
