As Homer would say..then the shaft sits in the cup of the right hand...
Usually, the only real difference between Right and Left Hand Grip is that the Clubhshaft lies under the heel of the Left Hand but it (or the left thumb) lies in the cup of the Right Hand.
I make a point of putting the shaft along the lifeline of my right hand (the cup) even though the thumb can't be there and remain happy
