To use this technique, you also need to set your camera to use a single focus point and use a technique called "focus and recompose". Select the place in the frame you want the focal plane to fall and use BBF to capture focus. Then release the back button and frame up the shot and then click the shutter release. If you use any other focus mode, you can get focusing errors as the camera, rather than the photographer, determines where the focal plane lies.
The only times that I do not use BBF is for night photography, where I manually focus and for action shots where the subject is moving towards (or away) from me, in that case I use a 3D tracking mode with AF-C.
