Depiction of waypoints on a LPV Approach by Jeppesen

I would like an explaination why Jeppesen on their approach charts will show the FAF and the stepdown fixes, if there are any, for the final segment with the symbol for flybye waypoints ? Since these are waypoints that are part of the final segment the aircraft will be following the VPA if this is an LNAV or LNAV/VNAV approach or it will be fullt coupled to P-ILS and P-G/S if this is a LPV approach. The approach will be captured on the FMS and scale-change will have taken place. These waypoints are clearly fly-over, but only the MA waypoints will be depicted with the symbol for fly-over. Jeppesen gives no spesific explanation of why this is so in their approach chart legend.
