You’re comparing apples and oranges. Volume is a value without implying any kind of progress. Time is progress, and turning clockwise gets you further down the progress of time. A scroll bar going up is something visually going up, but it’s not a value, and it’s not a measure of progress going forward. If anything, it’s going back, because you usually start at the top of a list or page that requires a scroll bar. So progress here would be scrolling down.

But I think any interface should make this sort of behaviour easy to configure.
