Actually, "1 revolution" is generally defined as "Not 2 revolutions". This is usually interpreted to mean that the pitcher's arm cannot continue up past her ear after she releases the ball. The same criteria is applied to the slingshot pitch as well, where there are "no" revolutions involved.
I interpret this to mean that after the pitcher separates her hands, she can swing the pitching hand down and back to almost the vertical position (pointing at the sky). From this point she can bring her hand down and forward, make a complete revolution amd release the ball on the second time past her hip (going forward), then follow through until her arm is again pointing mostly up as long as she doesn't get back to vertical again. That is if you assume that zero degrees is straight up, then she can swing her arm through ~710 degrees and still be ok.
