That of only true if Obi didn't cut of his fleshy arms.
Also, I always wonder if Vader CAN cast Force Lightning if He took off his mechanical arm and cast it with the stub... But that would look really silly wouldn't it?
And I think at that point its more like Anakin's Hatred(to Obi mostly) That keeps him alive more than anything else. Though I think hs love of Padme never ends.
