It argues pretty strongly (and I think correctly) that "delayed choice" experiments do not, in fact, imply any kind of retrocausality. The key is that all the effects of washing out and restoring interferences in quantum erasers, etc. are properly interpreted remembering that a beamsplitter doesn't actually measure anything. Instead, it passes a superposition state, and the crucial feature is whether we set up detectors to measure all the states in the superposition or only some smaller ensemble.
