This could be the case when that service call is done to a SaaS application and it is required to track on behalf of whom that service is called. The identity (user name) only is not enough when authentication must happen using the principle (security token) of the user, but there are applications that can handle this using some combination of a system user (or client id plus secret) with an on behalf of user. And there are situations where having an on behalf of user only is enough, like when storing data in a database table with audit columns (you don’t want all the end users also to be database users so passing on the user’s principle to the DB would not make sense).
