DuplicateEdgeCurves Method for Polysurfaces [SOLVED]

Hi,

I tried to use the Brep.DuplicateEdgeCurves Method (Boolean) from Rhino Common but I realized it works for Surfaces only but not for polysurfaces however in Rhino Python the DuplicateEdgeCurves works for polysurfaces as well. Why is the difference?

https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Geometry_Brep_DuplicateEdgeCurves_1.htm

    import Rhino
    import scriptcontext

    def DupBorder():
        filter = Rhino.DocObjects.ObjectType.Surface | Rhino.DocObjects.ObjectType.PolysrfFilter
        rc, objref = Rhino.Input.RhinoGet.GetOneObject("Select surface or polysurface", False, filter)
        if rc != Rhino.Commands.Result.Success: return rc

        rhobj = objref.Object()
        brep = objref.Brep()
        if not rhobj or not brep: return Rhino.Commands.Result.Failure
        rhobj.Select(False)
        curves = brep.DuplicateEdgeCurves(True)
        tol = scriptcontext.doc.ModelAbsoluteTolerance * 2.1
        curves = Rhino.Geometry.Curve.JoinCurves(curves, tol)
        for curve in curves:
            id = scriptcontext.doc.Objects.AddCurve(curve)
            scriptcontext.doc.Objects.Select(id)
        scriptcontext.doc.Views.Redraw()
        return Rhino.Commands.Result.Success

    if __name__=="__main__":
        DupBorder()
