The MAF measures air velocity at a point and through tuning, the designers were able to translate that into an air volume flow rate that is used to estimate how much fuel should be injected into the cyliners. The airflow through that section of tubing is important to the accuracy of the flow speed to flow rate conversion. There are so many variables involved that there's no way to tell if the car would run exactly the same if you move the MAF or not. Everyone who adds a new intake to the car also messes with the flow through the MAF tube a little, but the car sounds like it's still pretty happy with the results.
