ICAO Annex 14/UK CAP 168 only requires that a runway strip end (60 metres for a Code 4 runway) is obstacle free. A RESA extends beyond the strip.
The risk management of a RESA is the aerodrome operator's responsibility to ensure that vehicles do not pose a hazard or prejudice the runway declared distances.
I would suggest that the Doc 4444 definition infers that the manoeuvring area is that set aside as suitable for the normal ground movement when taking-off/landing/taxiing. The surface of a RESA does not fall within this. Furthermore the surface of a RESA need not be prepared to the same standard as the manoeuvring area/runway strip and is intended to assist with deceleration in the event of an overrun.
