I understand this the following way: when nobody claims "ownership" of a mistake, everybody (ie. in a team) feels guilty about it, even of they had no control over what lead to this mistake. If someone says clearly that it was his mistake, everybody else may stop worrying and either concentrate on something else or help mistaken person avoid such mistakes in the future. This has nothing to do with scapegoats, but my understanding can be, of course, completely off.
