I did some tests here (in RGBA-8bit) with Reroute, and Alpha Channel. It seems to work correctly. It is time consuming, for me, to post here the screencast/screenshot of the tests, but if you think it can be useful tell me.
It may be (surely) that Cin-CV and Cin-GG work slightly differently.  I remember that, when you are using Title effect, the black colour is meant to be the alpha channel (more or less).
It may be that not everything Cin-CV is able to do can be reproduced in Cin-GG,... and vice versa.

You can perform this convoluted method OR "just use a simple Outline font" which can be freely downloaded.

  Already with the default overlay
(Normal) the result is not exactly the same as in the tutorial. For
example, the outline of the letters is all white while in the tutorial
there are plays of light and shadows that make it three-dimensional.
But the worst comes when I set the center track to "Multiply": a
completely wrong color comes out!
 
 But I have growing suspection we really do some calculations differently, may be in more widespread/standard way but not like original Cin worked.
 
Agreed.  CinGG does some things differently as well as calculations.  That does not make them wrong.
