Using CUTG defined by toolbars graphical cut tool

ROOT
1

Hello,
if I use the “Graphical Cut” tool from a pad’s toolbar, I can “see” the created cut by using

root [23] gPad->ls()

Canvas Name=c1 Title=c1 Option=
 TCanvas fXlowNDC=0 fYlowNDC=0 fWNDC=1 fHNDC=1 Name= c1 Title= c1 Option=
  TFrame  X1= 0.000000 Y1=0.000000 X2=250.000000 Y2=250.000000
  OBJ: TH2F     MCvsRPEnHigh    MCvsRPEnHigh : 0 at: 0xa13e340
  OBJ: TPaveText        title   X1= -28.125001 Y1=262.208689 X2=52.209051 Y2=279.687503
  OBJ: TCutG    CUTG    Graph : 0 at: 0xa2e2d60

But I cannot use the cut:

MCvsRPEnHigh->Draw("[CUTG]");

draws the full histogram.

If I clone the cut with

CUTG->Clone("mycut");

the cloned cut works fine:

MCvsRPEnHigh->Draw("[mycut]");

Suprisingly, just to clone the cut is not enough

CUTG->Clone();
MCvsRPEnHigh->Draw("[CUTG]");

Is there a way to use the cut directly, without cloning the cut?
Cheers, J.

cutg1 = (TCutG*)gPad->FindObject("CUTG");
cutg1->SetName("cutg1");
MCvsRPEnHigh->Draw("[cutg1]")
