It used to be that once the fire service started 'deploying media' (that's foam and water, not old CDs and DVDs....) then fire cover was reduced. However, LHR can now cope with deploying media at one CAT10 (A380) incident and still have CAT10 cover for the rest of the airport.
Interesting, so in this case I guess it was just that the runway had to be checked after the aircraft vacated, and that flow was reduced to accommodate the aircraft incoming as an emergency?
