John, my guess would be that since the bulbs shared a common ground, The
electricity was going backwards through the second bulb, back through the
switch and seeking ground on the other side. I'd think that when both bulbs
were on, on the good side, the bad side would have been barely or non
existant. At that point whatever ground they had was what would light them.
They couldn't gain any ground from the other circuit.
