That doesn't seem right?
In such situation the result may not look good. But in general I think we have no other choice: first one has to be aware of all features (from all layers) that should be labeled. Once all layers have been rendered, the labeling algorithm is able to produce candidate labels (for each feature), compute their costs and finally resolve the label placement problem, returning a set of labels that do not overlap. Also, by default features act as obstacles to labels, so such candidates covered by other features would get higher cost (and may not be considered at all).
