Hard to say, as we are both firmly in the position of merely speculating absent any facts. What I tried to suggest was that there could be elements of the Pakistani government which continue to covertly support al Queda and the Taliban (namely, some members of ISI). Whether such covert support, if it exists, happens with the knowledge or permission of Musharraf is further speculation. Who knows?
BTW, it is just as reasonable to suspect our "Powellian" coalition building operates under similar (bifurcated) intentions. However, American thinking (and usually, our policies) tend to be more straight-forward and less duplicitous than Middle Eastern thinking and policies, which I like to think of as being a strength of ours, with certain exceptions made necessary in order to counter adversarial intentions of hostile nations at times.
