Ha! FFG did screw up on their "possible positions" diagram!
See my explanation here:
Basically, looking at the first image, the yellow "possible location" box after the left barrel roll with the 2-bank template should be moved BACK 1/2 ship length.
Just try and figure out how you should position the 2-bank template to end up in the top-most corner of the yellow box. You can't. And if you move the template backwards along the initial ship position, you end up OUTSIDE of their yellow box.
Similar problem with the blue boxes on the right. (And probably the green and purple boxes as well.)
Also, in the caption they mention a "right bank maneuver with a speed of 1", but in the image they use a right turn, not a bank.
