Although I am not an ATCO, here is my tuppence worth.
The reference you quote states:
3.5.1.6 The pilot-in-command of an aircraft,
receiving an instruction from ATC to change level,
must report:
a. when the aircraft has left a level at which level
flight has been conducted in the course of climb,
cruise or descent; and
b. when the aircraft leaves a level for which ATC
has requested a report.
The equivalent reference in AIP is ENR 1.7 - 4.1.6
My view, based upon that reference, is that you are still required to report "left" a level. I say "left" as I once asked an ATCO, over VHF, whether they believed leaving or left was the correct term. After consulting with others he quoted this exact passage as the basis for "left" being the correct term.
