ansible register with_items loop

Given a directory structure like this:
[user@testbox01 test]$ ls -al /app/psoft/test/*
/app/psoft/test/12.1.2.00:
total 12
drwxrwxr-x. 2 psoft psoft 4096 Feb 19 16:41 .
drwxrwxr-x. 4 psoft psoft 4096 Feb 19 15:08 ..
-rw-rw-r--. 1 psoft psoft   54 Feb 19 16:41 list.txt

/app/psoft/test/12.1.3.00:
total 12
drwxrwxr-x. 2 psoft psoft 4096 Feb 19 16:41 .
drwxrwxr-x. 4 psoft psoft 4096 Feb 19 15:08 ..
-rw-rw-r--. 1 psoft psoft   12 Feb 19 16:41 context.xml


test.yml playbook:

- hosts: all
  tasks:
    - name: gather list of files
      shell: ls {{ item }}
      register: files
      with_items:
        - /app/psoft/test/*/list.txt
        - /app/psoft/test/*/context.xml

    - name: use shell to print list of file paths
      shell: "echo {{ item }}"
      with_items: "{{files.stdout_lines}}"


output is:

[user@ansibleserver01 ansible]$ ansible-playbook -i testing-inventory playbook_playground/test.yml --limit testbox01

it should just print a list of files:
/app/psoft/test/12.1.2.00/list.txt
/app/psoft/test/12.1.3.00/context.xml
