These appear to be completely opposite to the way that are supposed to work in reality. A position report is delivered by the aircraft to a ground controller, usually when passing a waypoint. PF3 (and PFE before it) instead provide a position check by the ground controller to the aircraft. Either option 9 under Centre needs to be changed to read Position Check Request, or the verbiage needs to change so that it to something like <call sign> passing waypoint <waypoint> at <Zulu time>, flight level <level>, <waypoint> next.
I suspect that because all the voices are recorded and can't be easily changed in practise, the former option is the most likely.
Not a big deal but it's been bugging me for about the last six years!
