Sure, the result is the same. Its as I stated before u have to use draw3D to give ur text a Z position. Otherwise all text rendering is handled on the same z plane resulting in the observed "overlay-ish" behavior.

>and I need depth-test to be done between spheres and texts.
>Anyone knows if it's possible with 2d mode of TextRenderer ?

I guess u misunderstand the 2D/3D mode of TextRenderer. Actually the 2D "draw(CharSequence str, int x, int y)" rendering is using "draw3D(str, x, y, 0, 1);" internally. The only difference is that 2D draw() is setting the Z coordinate of the text billboard always to 0.

So theres no real "2D mode" of TextRenderer. U can safely intermix 2D/3D text rendering methods. To get what u want u have to do the following:

setup ur normal 3d matrix stuff
draw n spheres with radius r at x,y,z
beginRendering(screenwidth, screenheight, false)
z = (individual sphere z) + r + (some fixed offset_bias)
draw3D(str, x, y, z, 1)
endRendering()

Hope that pseudo code helped a little bit to clear things up ...
