It is documented: see this. Note that you have to look at the documentation for vision.videoFileReader in the Computer Vision System toolbox, and not the documentation for VideoReader.
Note also that there isn't a "step instruction" in MATLAB. step here is a method of the vision.videoFileReader class.

So far, Mathworks has avoided using step() as the name of any toolbox routine. However, it is used as the name of a method in a number of different location, so you have to look at the object type of what you are calling step() on to determine what effect it has.
