A two-box simulation gives different results with one or two pids

We run a simplified version of the Von-Karman test case. The modified simulation file is

2 1  GfsSimulation GfsBox GfsGEdge {} {
  Time { iend = 0 }
  Refine 6
  Solid (x*x + y*y - 0.0625*0.0625)
  OutputTime { istep = 1 } stderr
  OutputProjectionStats { istep = 1 } stderr
  OutputSimulation { start = 0.1 step = 0.1} simulation.gfs {
      variables = U,V,P
  }
}

GfsBox { id=1 pid=0
  left = Boundary {
       BcDirichlet U 1
  }
}
GfsBox { id=2 pid=1 right = BoundaryOutflow }
1 2 right
