I don't think that is > why quarter sawn wood is used, at all. I can see your point this is a bit misleading. But radial cut spruce is about twice as stable as tangential sawn spruce in relation to changes in humidity. You would clearly have a lot more problems with tuning stability and considerably more damage from compression set if you used flat sawn spruce. This doesn't mean there are not other considerations for the use of quarter sawn wood in soundboards, such as better tone (not sure) or easier to plane (for sure).
