Sudden drop in price..

I was just thinking if the intention of the short seller was to press down the price so that they can collect more shares at a lower price where for example they shorted a certain amount of shares but when the price went lower, they bought back 2 or 3 times more of the number of shares they shorted so that not only they already bought back enough shares to return to the lender but also made a handsome profit from the additional shares that they bought at a lower price after they pressed down the price?
