XML model WorkflowTask attribute I06 meaning

I hoped I’ve two identical XML exported models, but they differ in I06 attribute in several WorkflowTask items (targetType CZ.Advantages.Asap.Schema.WorkflowModel.UIFormTask). The value is zero. I didn’t find any difference in Architect. What is the meaning of this attribute?

Column I06 stores RefreshPortalAfterSave (if true, the client will refresh its menu after saving data).
