Yes, it should. Now, it's still probably better if you coded with aTrack->GetLogicalVolumeAtVertex, then get the LogicalVolume name and compared that to the names of the LogicalVolumes for your GOS and CsI. Mind you, this is a string comparison and thus slow. You could code it such that you don't compare string names but instead compare the pointers. For this you'd have to find the pointers (once in the StackingAction) with:
G4LogicalVolume* LV = G4LogicalVolumeStore::GetInstance()->GetVolume("CsI");
(assuming CsI is the name of the CsI logical volume).

Don't know....you have a bug somewhere ... probably in DetectorConstruction.
