If you look closely you can see the bottom of the battery pack shield protrudes slightly below the level of the car's jack pad surface. So the hockey puck allows you to clear that yet center the floor jack's cup on the jack pad's center (assuming you have one of those jacks with a wide cup)
Actually, to completely clear the battery shield, you need two hockey stacked. I have two floor jacks and when I rotate, I lift one side using 4 hockey pucks(two on the front and two on the back). It's possible to get away with just one, but then you have to make sure the lift pad doesn't overlap underneath the battery shield. By using two, you don't have to really be careful of this.
