Yes but there's much more required. For example, why does it get a standing person and not the chair or other things in the room? I suspect this is from a paper so you'd have to follow the directions in the paper rather than ask us.

Unless this is two examples of obtaining the difference of two images, with there being two constant-background images available that are not shown here?

What you are looking for is background subtraction. It is not really as simple as taking the difference between the two images. If you have a video taken with a stationary camera, then you can detect moving objects using the vision.ForegroundDetector object from the Computer Vision System Toolbox. See the Motion-based Multiple Object Tracking Example for more information.

That is what that example code does. Look at the example code setupSystemObjects() and see how it uses a vision video file reader to open a video file.
The example code detects the differences between frames and uses them to track moving objects.
