Be sure to look at every detail and expand your thinking. Early debunkers said they were not in the same hallway because the camera angle was different.
Looks to me like one image is rotated (black bar at top). Also, in both images there is no one else in camera. I've never had that happen except when I was almost missing my flight and was running.
Next, can the flight even board from two ramps simultaneously at that terminal? Doubt it, but needs to be accounted for.
