It looks like your images didn't load. Also you linked to an older version of the docs here is the one that matches your version, notice the 3.3 in the url. https://docs.godotengine.org/en/3.3/classes/class_meshinstance.html

A mesh can have different surfaces so when requesting a surface you have to specify which surface by giving an index. Consider a mesh with different parts (like a car with a windshield, the body etc) which have different materials, each part could be its own surface with different materials.
