Yup. One man's "overuse" and "source of mistakes" is another man's way to draw attention towards a region in the latent^H^H^H^H^H^H idea space.
This is useful and often good enough, because a) the rest of what's been said and situational context will help home in on more specific associations (and if not, one can always ask for clarification), and b) we often don't need to resolve specific ideas - "my friend is a samurai" may just be an invitation for the other person to reply "oh, fun, speaking of more ancient cultures, have you read about ...", and then continue jumping around big clusters of associations, without ever properly resolving any.
