Does the Shufi' have the right to claim based on the buyer's original oath if the buyer later retracts and affirms the seller's higher price?

Primary text

If the buyer later affirms the seller's claim that the price was two thousand, stating he was mistaken, there are two views on whether the Shufi' can still claim the property based on the price the buyer originally swore to. This is analogous to the situation where evidence supports the seller's price.
