Because in order to remove the pole (if there was only one person) they would have to do it slowly otherwise they would bleed out. They would have to surgically repair while removing the pole. Since the two were stuck together they couldn't do that. So, they had to choose one to remove from the pole first (thus causing them to bleed out). I sort of hoping that Meredith would perform some miracle and save the girl too,
