in terms of leverage, it would be the opposite, but it is correct in terms of body mechanics. the further a force is applied from the point of rotation, the more torque is generated. like when using a wrench - if the bolt is stuck, you lengthen the handle. the disadvantage probably comes when the longer-armed one has to bend his wrist at an uncomfortable angle to reach the other's hand. or, when the longer armed one has to hold his hand out further from his body - that would decrease the amount of chest muscle utilized.
