I just thought of something: that tutorial is pretty old and nowadays you can probably simply use Cryptomatte:
And while we’re at it: here’s a better way to ‘de-saturate’ an image:
If you make the saturation zero in a HSV Node (or in a Hue Correct), then you are left with the Value and for instance ‘pure blue’ and ‘pure’ yellow both have a Value of one, but yellow looks much brighter than blue (for most, if not all humans) and the RGB to BW Node calculates the luminace (‘perceived brightness’) and shows yellow as lighter than blue, when converted to greyscale!
