I've seen this before with the SVX, quite a few times actually.
It has to do with the Power mode. It's nearly always people who know sweet FA about engines. They know when they floor the wellie the Power Mode light comes on and the car goes whoosh, and they rationalise this as being the onset of a supercharger or sometimes they think it's a turbocharger.
In the many cases I've seen through the years they don't seem to be trying to deceive, I think in most cases they just don't know any better.
