If you do not compensate for that while driving the robot, then yes, that is what it would do. But if you start driving forward and start to rotate to the right, if you move the left (transversal) joystick to the more to the left, you can compensate for the spin and more or less the robot will continue to move "forward" while spinning. With only relative control, it takes a lot more driver skill to translate while transversing.
