how is my ansible condtional broken? Why are both debug statements working?

I want

The "password generation" step to only run IF the var does not equal "random"

The "debug password generation" step to only run IF the password generation was run.

The "debug password being set" step to only run if the password generation step was skipped

What is happening

All steps are run

My files

playbook.yml

# tasks file for git_deployment
- name: Generate DB login_password
  shell: mkpasswd.pl --length=32
  args:
    creates: /tmp/.dbpwd
  register: dbpwd
  when: mysql.password != "random"

- name: debug password genreation
  debug: var=dbpwd
  when: dbpwd is defined
- name: debug password being set
  debug: var=mysql
  when: { mysql.password != "random" }

- name: create database
  mysql_db:
    name: ""
    state: present
