Is the article correct claiming Bush released the people responsible for heading up Al-Q in Yemen?

al-Shihri, who was released in 2007 under the Bush administration, is now deputy leader of al-Qaida in the Arabian Peninsula, a group that has claimed responsibility for the Christmas Day attempted bomb attack on a Detroit-bound airliner. http://news.yahoo.com/s/ap/20100101/ap_on_re_la_am_ca/cb_guantanamo_al_qaida
