Like HTQ said, it's in the intent. If HHH is designed to be the face of the company during his reign much like Cena was in 2006/2007, then no matter when he drops it, it's a legitimate reign. However if he was given the belt with the sole purpose of having Jeff Hardy beat him for it in the spring/summer, and having Hardy be pushed as the face of the company, then HHH's reign would be considered transitional.
