No, I'm actually fairly sure that the majority of users expect the control to go to where they click when they click on an explicit location on a slider-like control. See: media player seek control.
While I've never used the Windows volume control in the way he describes, it does not violate my expectations. I expect clicking within the slider track to set the slider to where I click, and for the slider to follow the mouse when I drag, but I expect clicking outside of the slider track (for instance, above or below, as he describes) to be implementation defined, although if it's not marked it might not be very discoverable. A scroll bar is an example of a slider that behaves exactly the way he describes, and is marked as doing such.
