Kinda, but all other joint errors will be resolved gradually as well, so
it will affect all aspects of the simulation, not just penetrations.
  
It's almost as if the Novodex code allows one to adjust the error
reduction for contact joints separately from the error reduction of other
types of joints.  It seems to be different than ERP though - penerations
are resolved with constant velocity.
