See FatFingers.cpp 

354             
355 bool FatFingers::checkForClickableElement(Element* curElement,
356                                           Vector<IntersectingRegion>& intersectingRegions,
357                                           Platform::IntRectRegion& remainingFingerRegion,
358                                           RenderLayer*& lowestPositionedEnclosingLayerSoFar)

our intersection area is a region. Every time we have a higher zindex'ed layer, we subtract that layer's area from the "remaining intersection region", once we are done with it.
