The rules I have say that the crop is placed on the lowest numbered card at the START of the auction phase.
Your way is mostly equivalent I think, except e.g. if the Shuffle card comes out and causes the lowest card to disappear: then in the next auction there would not be a card with a crop even though there's supposed to be.
