This isn't land and hold short as would be practiced in the USA (i.e. to instruct an aircraft on approach to land and hold short of a crossing runway to allow independent ops)
This is about requesting a pilot, after landing and while decelerating, or even after stopping, as it says in the third section, to hold short of an intersection. Only once that is achieved (i.e. holding short), would the controller then commit something on to the runway in front of the holding aircraft. This is mainly aimed at holding short of a cross runway during backtrack, as it says in 19B3(3)
