I think you're right. The word "to understand" has two meanings. In the narrow sense, it's the feeling that we have when we "get it", that is we think that we have built a correct model of reality and it passes the logic consistency check (which is verified by being able to give an example or counterexample). In the broad sense, it means to build and apply correct models of reality.
Above, I am talking in the narrow sense. So the fact that the model itself is wrong shouldn't be an issue. But in the broad sense, we could say that understanding is ability to convert between intensional and extensional (ostensive) representations (models) of the world. Finding an example from intensional representation is just one task that is required.
