The list is the result of subjective listening to the files produced. Even though it might be a 'bit perfect' copy, that doesn't mean that the original disc & its burned reproduction contain the exact same information. Errors can be introduced in the CD stamping process or in its playback & these are reproduced or error corrected in the burn process. Error correction is not exact. It reads an error & fills in this data point with a synthesized approximation of the missing data. If you use EAC, you can watch the EC in action. Some discs will only light up the EC box briefly while others will quadruple the burn time or - in some cases - fail completely. As well, the burn copy actually has better definition of the 'hills & valleys' of a disc when compared to the stamped original. But . . . they might not accurately represent the original digital music file as well, although in practice they usually sound better (subjectively again).
Kind of like scratches or spilled beer or seed burns alter an LP's grooves & the ability of a stylus to wiggle through them . . .
