Yup, but what the drawing also depicts is the fairly standard technique with pulleys on aircraft design, which is to make them as large a diameter as it is necessary in the available space, in order to avoid bending the cable too much, which causes fatigue in the wire if too tight a radius. So if you are trying to determine a pulley diameter, or routing, you know that one is large enough to not stress the wire through a bend.
