Question Muon Capture in Physics list

Hi All,

I have a question on the muon capture process. In a simulation I am working on we have these lines of code for muon capture

if (particleName == "mu-")
{
  G4VProcess* aG4MuonMinusCaptureAtRest =
       new G4MuonMinusCaptureAtRest();
  pmanager->AddProcess(aG4MuonMinusCaptureAtRest);
  pmanager->SetProcessOrdering(aG4MuonMinusCaptureAtRest,idxAtRest);
}

but in the Underground Physics example it is done like this (lines 327-329)

if( particleName == "mu-" )
  pmanager->AddProcess(new G4MuonMinusCaptureAtRest(), 0,-1,-1);
} 

These actually seem to be doing the same thing to me, but in my simulation muons are forced to decay AND capture at rest, they always do both. This was easy to identify because there were more than two outgoing neutrinos at the end of the track. Is there something wrong with our process ordering?

Thanks a lot, John
