You're on the right track
Having button cutouts on both sides of the case at the same location reduced the ability of the case to resist bending. However the apple logo on the back of the case is in the same plane as the buttons as well. The logo is milled into the outside of the case but a pocket is milled out in the same location on the inside of the case to allow clearance for a protrusion from the battery. The thickness of the case back in the area of the logo is VERY thin, further reducing the ability of the case to resist bending.
