In one of their explanations they say:
For a fixed anatomical degree of mitral valve incompetence producing mitral regurgitation and at a given left ventricular preload, an increase in contractility would tend to increase LV afterload.
Maybe I forgot all my physiology, but I can't even find one source that explains why an increases in contractility -> increase in afterload
