Plagiarism, kind of

I agree. He tried arguing his case but they basically  said "too bad, that's the policy". They let him rewrite the paper by the next day for half credit. He was pretty pissed and said he didn't feel in the least bit bad about what he did. 

It's hard to believe that his actions were what they were after when they wrote the policy.

There are a limited number of combinations in which a sentence can be written in a given language with a given vocabulary. The more people live in the world, the more they write about the same topic, the greater the chance of repeating ("plagiarizing") the same sentence, from someone else living in the past or present.. and you can't have a clue about it..

I am glad to report that he apologized for the cheating. The peace is restored.
