Creative does the same sort of thing in the positional sound configuration of their Live! cards... You have the listener at the center, and position the various sound sources around the 'soundstage'.. So when I think of shifting a sound to the left, I think that it will sound like it's left of wherever it sounded before.. As I'm to the left of the center of the speakers in the car, I would expect it to sound more centered to me.. I care not about the delay or whatever magic is used to make it work..
