It caught my attention but may just be a minor slip of the tongue.
I'd be surprised if any of the differences between the -700A and -700B turn out to be relevant to the NTSB's investigation, so referring to the aircraft as a generic -700 to differentiate it from earlier and later series seems perfectly reasonable to me.
