What are the voltages at the gain resistor pins of an AD620 ?

My EVAL-INAMP-62RZ evaluation board user guide says that the outputs of the guard drivers should be equal to the input voltages plus 0.6V, i.e., the same as the voltages at the gain resistor pins of the AD620, but what I am measuring at the guard drive pins are -0.5V at each pin, same as at the ends of the gain resistor. Is this simply a typo in the user guide ? My circuit works fine otherwise.
