I am afraid that I find this a little bizarre.

As I understand it; job_service.get_self() returns a representation of 
the _local_ client application which has instantiated the job_service 
object (is that correct?). This would allow the client application to 
perform operations upon itself via the 'job' interface.

This raises several questions (how and why), but I am unsure if my 
understanding is correct.
