What does Levin mean at 5.15 in kinematics that had he reversed the zero point he would get the same average velocity but different curve?

Graphically, average velocity is the slope of the graph between any 2 points. I think when he said that, he meant that it doesn't matter where the graph started on the y-intercept; the average velocity (slope) between the 2 points would still have been the same, as the graph would only be shifted up or down. I don't think it's really important though.
