Paired on the measurement’s name only, which cannot know that three span lengths sum to the deck length. Step 3 works these out properly for every item it matches — reading every crop behind the item, deriving what the drawings imply and showing its arithmetic. This item has not had that pass yet; the button runs it for this one.
