No the question appears: Why should one use different parameters for two and 
threepass mode. Why not use the same vpass=3 for twopass-mode as well. (And 
then possibly rename this to vpass=2 but with new meaning). Does this make 
any difference?

Or in other words: Does vpass=3 has any significant disadvantages compared 
with vpass=2 in second pass of twopass encoding?
