Wasnt there a bug that prevented using blendmodes within groups or something ? It seems to work now.

I guess there are many ways on how to colorize an image, but is this the same as mixing channels ?

Yes, a long at the coeffs in the mixer are positive values. The mixer also gives you the ability to keep the luminosity, but this method allows you to tweak the coeffs later by adjusting the color layer opacity.

Why is that ?

Because the channels are greyscale... More generally, Color>Components>Decompose can generate several decompositions, and in most decompositions a color wouldn't make sense, and even when they do (RGB decomposition) things could get complicated: what should happen on recomposition if you add green in the red channel layer?
