I also initially thought the same thing. Page two of "Parallel and Concurrent programming in Haskell" maybe says it in a nicer way:

>A parallel program is one that uses a multiplicity of computational hardware ....

>concurrency is a program-structuring technique in which there are multiple threads of control...

(a pdf can readily be found with your favorite search engine for the full extract :) ).

I would much prefer to see a precise, rigorous definition and then examples (or eg and then defn is also acceptable), instead of just a list of examples. Examples help you understand a rigorous statement. But, if you only give a hand waving explanation for something, I think it just creates more confusion in the end, as you never know exactly what is correct. It's leaving it open for ambiguity.
