Correct. VR is turned on only by the shutter button.

Regardless of which button is doing the focus, VR takes up to 1/2 second to stabilize. You will see this in the viewfinder as the image jumps around. This is why sports shooters always have VR turned off; they cannot have this 1/2 second lag. Plus, at the shutter speeds they are shooting at, VR is not needed.
