It's been a while since I was AED-certified, but positioning the pads on the front of the chest and the back was recommended for infants, who may not have enough space to position both the pads on the chest.
But in a different class, I learned that it can be hard to roll someone over in order to position the pad on their back, especially if they are larger than you. If they have a suspected neck injury there can be significant risks.
