Double clicking on an edge will cause it to expand to the edge of the window. The shift + option trick doesn't just expand to the first edge it hits, it looks like both edges expand as much as possible.
So when combined with double clicking on a window corner, that makes all for edges expand to display size (even if the window was partially off the monitor).
