Additional explanation of "same-spin" concept is usually used on horizontal spin(i.e. side spin), that is, if you look from the top of an incoming ball,
if it is clockwise, you put your paddle in front of your body (parallel), the ball will spin to the right. So if you receive the ball with side swipe your paddle to your left, it will be "same-spin" the ball. If you swipe to the right, it will be against-spin. All above is talking about from top view point.
So when it talked about same-spin or against-spin, it should be more concerned with side spins.
