Hi Quinn, Technically this is not really hard to do but it is very tedious to line them all up. You understand that the photos came from several photographers shooting the same scene at different angles. This is what allowed them to be so fluid. If you are trying to do this alone with just one camera, that will be your first challenge.
As for the technical aspects: You could use Track Motion with Pan/Crop to overlay the images. What you would do is place each image on a new track. Each image will be a little further down the timeline but still on it’s own track. The way you get multiple on the screen at the same time is by overlaying there start times on their own track. Then you would use Pan/Crop to isolate the part of the image that you want to reveal. You need to turn off: Stretch to fill frame, and Size About Center, and probably Lock Aspect Ratio to be able to crop them properly. Then use Track Motion to position them exactly where you want in the frame.
Notice that each new image lines up with a part of the previous one. This is what gives it the continuity. I would download the video and load it into Vegas and examine it frame-by-frame so you can see what they are doing. Like I said, it’s not hard once you understand how Pan/Crop and Track Motion work.
