Food Stamps cards are essentially debit cards; so it's not a problem to scan the item and let the "system" accept it or reject it. If accepted, the purchase goes right on thru. If the "system" questions the purchase, a store mgr/supv is suppose to verify the purchase. I wouldn't be surprised to learn that some purchases aren't properly verified, i.e., soda and other snack foods. So, to me this restriction on sodas is a step in the right direction.
