I will not answer for him, but I can give my feeling about it. Perhaps  
some of these may contribute to the problem you raised:

-) the scattering amount needs some tuning
-) the real 'useful' atmosphere might be thicker than that of TerraPOV.  
Upper atmosphere low density is negligible from ground but may be not  
negligible from outer space. It might have a significant contribution in  
the integration in the latter case
-) the behaviour we have can be due to position of the sun relative to the  
planet and camera, and be normal...

What is certain: I'm not sure ...
