I'm a former perceptual psychologist but I don't see the need for this method. A simple fat border with a drop shadow would make it clear enough that the popup is in front the main window - interposition is a very powerful depth cue. I've also heard rationale along the lines that it focuses attention, but I don't see a need for that either since the spatial extent of our attentional focus is rarely bigger than a popup and the motion cues that occur when the popup appears should be sufficient to draw attention to it. Perhaps designers want to make it clear that the underlying window is not interactive - I can see some value to that. Personally, I feel it is overkill that masks the context too much. However, the convention seems very appealing to designers - I think I am failing to talk my fellow mobile designers out of it.
