Yes that is correct. The easiest way is to use a 0° block with the included anti-squat washers under the front screws to make it 1°, or a 2° block with the washers under the rear screws. If you want to have 1° of anti-squat of course.
I really don't see the point of flipping the block.
Btw: 0,1mm = 0,2 degree anti-squat difference, in case you want something in between 0° and 1°
