Have you actually seen this happen? Don't believe it - the code reads:
MeanNumberOfPhotons = ScintillationYield*TotalEnergyDeposit;
G4double sigma = ResolutionScale * std::sqrt(MeanNumberOfPhotons);
NumPhotons = G4int(G4RandGauss::shoot(MeanNumberOfPhotons,sigma)+0.5);
TotalEnergyDeposit has unit 'energy' and so MeanNumberOfPhotons comes out to be the same no matter how you have specified "SCINTILLATIONYIELD"; e.g. as 32./keV or 32000./MeV.
I just verified this with OpNovice (formerly N06).
