I hope this is fine for you

I appreciate you for doing that, but I do like to know how to do the process itself, so I don't have to ask again.

Open the _EyeNor-texture in Gimp and choose "Colors > Components > Decompose...". Set the Color Mode to Alpha and hit OK.
Then you get the same result as the _EyeNor_Alpha-texture.
