Van Rooijen disputes Confortola's version of the events. Van Rooijen, who had seen Confortola and McDonnell helping the stranded Koreans and their guide from below, thinks McDonnell did not climb back up the mountain, but rather climbed up to the highest anchor supporting the three stranded men to try to transfer the load. He then could have returned to the three men and may have spent another several hours alone helping free the men from the ropes. In his book Surviving K2, van Rooijen provides some photographs he believes supports these claims.
