Got a source for that?
When you wage war against America, isn’t that de-facto renouncing your citizenship?
My understanding is he publicly renounced his citizenship more than once. While that is not the same as formally renouncing it, it's good enough for me and the vast majority of Americans.
Any American who goes off and joins up with terrorists to plot, plan and encourage attacks on the US effectively makes them an enemy combatant open to US military attack. Sitting around trying to pick out the idiots that had/have US citizenship is to live in a world of theory and fantasy. The war on terror is just that, a war - not a police action.
When you make war on the country of your birth, yeah, that’s called renouncing your citizenship.
And YOU have to figure out wether or not this is a war.
When your figure THAT out, all will become clear.

He renounced his U.S. citizenship and all benefits thereof derived when he pledged loyalty to Al-Qaeda, Al-Qaeda being at war with the U.S.
