From your description, it is not clear what are your doubts.
The momentum direction is defined with respect to the world frame.
It may help you to define a particle with starting direction along one axis and run an event with tracking/verbose 1.
This will print you the characteristics of a track in each step, including momentum direction.
You can also visualize the track, as it is demonstrated in basic (only in Geant4 9.5) or novice examples.

Best regards,
