It all depends on how your mind works. Graphically or textually. Left brain or right. Software developers tend to be predominantly left brain oriented so it is not surprising Apple's documentation is textually dominant. Those diagrams come from Apple users on a graphics oriented web site which implies a far more right brain orientation.
Abstractly, that makes sense, but as a real life situation, I can't think of a single instance in which a procedure that involves options and is presented as a graphic would be more clear as text.
The idea of Apple's Human Interface Guidelines - although this instance may
be considered outside of their purview - should be to coddle Mac users, not Mac developers.
