You can interpret it any way you like, but the operator's OM-B overrides any FCOM statements.
At my outfit, the SOP has been brought in line with the Airbus recommendation to achieve 50% thrust before brakes release on a STATIC take-off, rolling take-off is permitted however.
So waiting on the runway for T/O clearance, use the static method. Otherwise, use the 'old' method. If it differs in your company ops manuals, just do what they say. But they will usually override the FCOM if different.
