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.
