When you get right down to it, it is basically saying the wave functions of the entangled photons do not decay since they are never directly observed. Extrapolating from this one can say that in fact Wheeler and Everett were right, and the wave function never decays at all. Which of course leads to the "branching universe" idea, which to me will one day be seen as no more surprising than the "many galaxies" idea. Remember, the idea of other galaxies before the discoveries of Hubble and so on used to be only speculation, not universally held. Now we know there are at least 10^10 galaxies. Similarly the fact that the wave function never collapses, as Everett and Wheeler proposed will be held to be just as prosaic as the fact that there are other galaxies.
