That is not correct. The desktop profile enables qt4, because it is a reasonable default (for qt-only packages, USE=-qt4 means "don't build any gui", but desktop users always expect some kind of a gui by default, whether it's gtk or qt*.) The result is that qt4 is enabled in child profiles of desktop - gnome and kde and plasma. Since plasma enables qt5 and does nothing with qt4, you have all qt versions enabled there. And when popular qt5-only, gui-optional packages appear in the tree, we will need to enable qt5 in desktop profile too.
