"selects between 'normal' mode (which includes automatic panning detection), and 'active' which is designed for shooting from a moving vehicle. Again the lower switch is distinctly small."
The "active" switch for IS/VR is for panning. It turned OFF VR for horizontal axis, so the VR won't interfere with your deliberate movement when panning.
