Yes, but how do you know that moff tiaan jerjerrod was on it when it blew up?? Remember that the guys were evacuating on it at the ending; nothing ever confirmed whether or not grand moff tiaan jerjjerod escaped!!!!
Check the deleted scenes on the blu-ray. They were about to blow up the moon of Endor when the Death Star was destroyed, so no, he didn't escape
