Never test camera focus issues on a object that can move. When testing a camera for focus issues never shoot slower than 2 to 3x slower than the focal lenght you are using unless you have the camera on a quality tripod and are using timer mode or a remote shutter release. Never test focus issues with a camera set to any other mode except for single shoot, center focus point only unless you are testing for something specific to another option.
You do realize that the camera doesn't know you moved it don't you? You could focus lock on a specifc spot, recompose, and then recompose back onto the initial spot and the camera wouldn't know it. You can put your camera on a tripod, focus lock, remove your finger, and turn the lens to manual focus and the spot you focused on should still be in focus.
All that being said, retest your 50D with a more stable subject and with a tripod if at all possible to prevent any chance that you are moving your camera a little forward or backward.
Good luck.... hope it works out.
