There's no difference in the doors.Honestly I'm not even sure, I wonder if it's because these were originally manual doors.
It did seem to me when I was by your passenger door, that the glass wasn't being held forward properly.
Anytime that the door glass slides backwards out of the front channel, there will be problems with tracking. The front channel, (division bar) holds the glass centered between the outer seal and inner felt wiper, (for the most part) when the window is not completely up.
