It's more that the parts look as if they should be opposites, but the wholes turn out to be completely unrelated. The incongruity makes you do a double-take.

It's part of the perils of using idiomatic language. (My ninth grade French teacher tried to cure us of literal translation by asking us to translate, word by word, the sentence "I was left behind." Snickers everywhere...)
