[TIDL}Why TIDL_fillDataBufPadRequirements() set pad above 1?

void  TIDL_fillDataBufPadRequirements(sTIDL_Network_t * tIDLNetStructure)
{
  int32_t i, j, k, l;
  int32_t padW, padH, curPadW, curPadH;
  int32_t foundInData;
  for (i = 0; i < tIDLNetStructure->numLayers; i++)
  {
    for (j = 0; j < tIDLNetStructure->TIDLLayers[i].numOutBufs; j++)
    {
      padW = 1;//:TODO: Temporary change to make same padding for all layers in mobile to be 1
      padH = 1;//:TODO: Temporary change to make same padding for all layers in mobile to be 1
      for (k = i + 1; k < tIDLNetStructure->numLayers; k++)
      {
        ......
      }
      tIDLNetStructure->TIDLLayers[i].outData[j].padW = padW;
      tIDLNetStructure->TIDLLayers[i].outData[j].padH = padH;
