The way membrane roofs work is by their overlapping design. As the previous layer is covered by the next it creates stair step water shed design, disallowing seepage and water backslaps. This stair step design also has a vertical component to it. If each row is not offset correctly, water may enter the system through “T” joints. It is standard practice to stagger each row of membrane.
