I'm in agreement with Musket90 that old not bold may be confusing RESA with Stopway. Every inch of the Stopway must be able to support the weight of the aircraft, although it's surface MAY be damaged by the aircraft.
RESA poses a physical constraint on how much of the Stopway may be used for in determining the accelerate-stop performance of the aircraft. As an example, for the airports that I work with, although the Stopway may be, for example, 150M in length, not more than TORA+60M may be used for the Accelerate-stop performance calculation.
