What is block's rescue supposed behavior?

[Konstantin Suvorov]

Hello.

    - block:
        - fail: msg=fail
      rescue:
        - debug: msg=rescue
      always:
        - debug: msg=always

     - debug: msg=after-block

Seems rescue block bring node back into health state and continue execution of tasks, so after-block debug is executed (tested with ansible 2.1 RC4).

If I add fail task inside rescue – it will stop execution after always task.

Is it supposed behavior?
