The S92 has the option to pick up a 'crew' route: you get two different pages in the FMS, 'user routes' and 'company routes'. The former can be modified/deleted at will, not the latter (just like you can save 'user waypoints' for repeated use).
The Commander programmed the “APBSS (Blacksod South) Route” (See Figure No.4 above) into the FMS during the cruise and the Co-pilot confirmed that the route matched the Operator's Route Guide.
So they obviously didn't just blithely pull up the waypoints left in the FMS database from a previous task, they deliberately selected a saved route and checked it against the route guide.
It all depends on what the first sentence really mean:
1- pilot selects APBSS from the 'user routes' page.
2- pilot selects it from the 'company routes' page.
3- pilot enters every waypoint in turn directly.
