"Automatically close case when all-to-dos are complete" does work

[Larry Lau]

I have HR Service "Employee Equipment Preference" configured to close case when all to-dos are completed. However, when the only task is completed, the state of the case stays in ready state. 

The "Assigned to" user does receive the following email saying all tasks for case is completed. But I was expecting the case to be closed automatically without human intervention.   Is it not how it is supposed to work? Anyone knows if this is how it is supposed to work.

Thanks

There is a scheduled job: "Auto close case" that closes the cases - for testing purposes it can be manually triggered ...

Ootb it runs daily at 3am.
