    VbG=3V

    VaG=2V

    Hence Vba=VbG-VaG=1V

    Looking into terminals ab with the voltage source considered a short and the current source considered an open circuit, one would see a total resistance of 2Ω||2Ω + 1Ω = 2Ω.

    So the equivalent circuit at ab is a 1V source in series with a 2Ω resistor.

    The bottom link is just the ground (G) reference.

    Actually, I think the bottom link is not the ground reference. I think the G node disappears when you add the two 1Ω resistors in series.

    That's true. The G link is "hidden" in the right hand equivalent circuit.
