Q. How do I mount my cartridge in relation to my tonearm?
Answer:
It is only necessary to adjust the arm height until the arm tube is parallel with the record surface, in order to set the correct stylus rake angle (SRA). Therefore the written instruction is correct and the diagram, although a bit misleading, is also correct as it shows a line parallel with the top of the cartridge (even though it is located at the bottom) which in turn is parallel with the arm tube.
