Scotch Grain Whisky... Whisky or Neutral Spirit?

I've been skimming sources outside of my note card compilation, just to give me some variation to the redundancies, and just read in Grossman's Cyclopedia (Ó 2002) that "Grain whisky in Scotland is whisky and not neutral spirits, as some people believe."  They then go on to say that this grain 'whisky' is "distilled out at slightly over 180 proof."

    If it's distilled out that high, how is it not neutral spirit?  Is the aforementioned statement more about pride, than matter of fact?  Just curious of your thoughts.  Off to do some more in-depth search myself...
