Bush is not ignorant he's CIC. As he constantly goes on about, the nation is at war, you don't change CIC's at a time of war. This is indeed epic lulz.
Furthermore, this is not just of academic importance. The substantive effect of the president being CIC has enabled the executive to effectively unilaterally declare war without Congressional approval, evidenced by a long bloody history in Latin America and Indochina that is so obvious it doesn't even need to be discussed. In the words of Dean Baker, it would have been useful to point this out to readers.
