i haven't done it, but i have heard about the technique. you use two
strips, probably 1/8 or slightly thicker, and apply them on the
rafters on either side of the joint. this creates a low spot at the
joint and makes finishing the butt joint easier. i think you need to
make the strips a little wider than your sheet so it fits under the
adjacent course.
