Does AI Servo work with back button focus?

What is AI Servo mode in Canon?
What is AI-Servo AF? AI-Servo AF tracks moving subjects. You half-press the shutter button to tell your lens to start focusing – then, if the area under your point of focus changes, your lens refocuses continuously until you take the photo. (On non-Canon cameras, this autofocus mode is often known as AF-C.)
How do you focus then recompose?
Focus and recompose simply means choosing your camera’s focus by depressing the shutter half-way with your subject centered in the frame, and then “recomposing” your image by moving your camera while keeping the shutter depressed.
