Superimposing a TProfile on a contour plot of a bi-dim histo

Hello all,

I got a TProfile which I want to plot on top of a TH2F:

2d_histo_et_vs_y.Draw("opt") ;
profile_et_vs_y.Draw("same") ;

I can do it without problem if I plot the bi-dim histo with options:
*-*    "ARR"    : arrow mode. Shows gradient between adjacent cells
*-*    "BOX"    : a box is drawn for each cell with surface proportional
to contents
*-*    "COL"    : a box is drawn for each cell with a color scale
varying with contents
*-*    "COLZ"   : same as "COL". In addition the color mapping is also
drawn
*-*    "CONT1"  : Draw a contour plot using line styles to distinguish
contours
*-*    "CONT2"  : Draw a contour plot using the same line style for all
contours
*-*    "CONT3"  : Draw a contour plot using fill area colors
*-*    "SCAT"   : Draw a scatter-plot (default)

But the TProfile does NOT appear on top of the bi-dim histo if I plot it
with options:
*-*    "CONT"   : Draw a contour plot (same as CONT3)
*-*    "CONT0"  : Draw a contour plot using colors to distinguish
contours

(BTW remark that the indication "(same as CONT3)" should be "(same as
CONT0)" at page http://root.cern.ch/root/html/TH1.html#TH1:Draw )

Is there any reason why ?
