To me, Nationalism and Patriotism mean different things.

At least to me:

Patriotism: the belief in the ideals of your country, in its people and its ability to strive towards that ideal state.

Nationalism: A strong identity tied to ones nation as it exists today (or in the past) at the exclusion of others or other thought

I agree with your definition, but I don't think the author is using "patriotism" literally this way.
