Get the Caller Playbook directory name in ansible

I have two playbooks pb1.yml and dir/pb2.yml. I am calling pb2.yml from pb1.yml playbook. I need to print the name of the directory which called the pb2.yml playbook. 

cat pb1.yml
---
  - hosts: localhost
    tasks:
      - debug: var={{ playbook_dir |basename }}

  - import_playbook: dir/pb2.yml

cat dir/pb2.yml
---
  - hosts: localhost
    tasks:
      - debug: var={{ playbook_dir |basename }}

In the following example , I am able to get the directory name of pb2.yml but I am interested to know the directory name of pb1.yml from pb2.yml. 

home/monk>ansible-playbook pb1.yml
PLAY [localhost] *******************************************************************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************************************************************
ok: [localhost]

TASK [debug] ***********************************************************************************************************************************************************
ok: [localhost] => {
    "samples": "VARIABLE IS NOT DEFINED!"
}

PLAY [localhost] *******************************************************************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************************************************************
ok: [localhost]

TASK [debug] ***********************************************************************************************************************************************************
ok: [localhost] => {
    "dir": "VARIABLE IS NOT DEFINED!"
}

PLAY RECAP *************************************************************************************************************************************************************
localhost                  : ok=4    changed=0    unreachable=0    failed=0

Expected result:

from pb2.yml, print /home/monk/

Either the variable is properly expanded and the value printed with the parameter msg

  - debug:
      msg: "{{ playbook_dir|basename }}"

, or the variable is printed with the parameter var without expansion

  - debug:
      var: playbook_dir|basename

Explanation

The code {{ playbook_dir|basename }} evaluates to "sample" or "dir" respectively

tasks:
  - debug: var={{ playbook_dir|basename }}

Such variables are not defined and the play will fail

"samples": "VARIABLE IS NOT DEFINED!

Quoting from debug

var: A variable name to debug.Mutually exclusive with the msg option. Be aware that this option already runs in Jinja2 context and has an implicit {{ }} wrapping, so you should not be using Jinja2 delimiters unless you are looking for double interpolation.

"Double interpolation" is actually "indirect addressing". The play below

- hosts: localhost
  vars:
    x: y
    y: z
  tasks:
    - debug:
        var: "{{ x }}"

gives

ok: [localhost] => {
    "y": "z"
}
