Why wouldn't it? The bearings show where the target is (and was). In step 4 Alcibiades has just drawn a line in a random direction (well, from bearing 1 over to and across bearing 3). Look at step 5 to 8. Using the circle and line parallel to bearing 1 he corrected the NW line to the correct course. It doesn't matter where he comes from or it's actual course being totally different. The circle and parallel line will show if it is a wrong guess, and what the right course is.
