Their redrawing a perfect example of the muddy thinking about signal 
common (what we call "ground" in a circuit). In his EMC classes, guru 
Henry Ott, WA2IRQ, emphasizes the importance of knowing where the return 
current is flowing -- he talks about the hidden schematic concealed by 
the ground symbol.
