It's context. Most people who know about football (or soccer to Americans) will know the World Cup refers to football, like the World Series refers to baseball. So with that knowledge the statement is put in to context.
The term "cotext" refers to the text that surrounds a passage, i.e. the words or sentences coming before and after it.
It's very similar to context, trying to explain the difference can be difficult, I guess context has a wider meaning in that it's not limitted to text or speach but can include the social situation in which a statement is said.
For example if someone is reading the sports section of a newspaper during the worldcup period you could ask them "How did Brazil do yesterday?" and it would make sense in context, but if you ask that same question in a different situation the context would change and it may not make sense. However there's no "cotext" in this situation as the question is stand alone.
