Set hosts value with an extra-vars doesn't work for my Ansible role

I've got a problem with my ansible playbook :
My playbook is composed of 5 roles and looks like this :
---
- name: Création de la machine virtuelle {{ Host_Name }} à l'aide du template {{ vcenter_template }}
hosts: localhost
gather_facts: no
roles:
- roles/VMWare/deploy
tags: deploy
- name: Configuration de l'échange de clé de root@lrtstfpe vers root@{{ Host_Name }}
hosts: localhost
gather_facts: no
roles:
- roles/VMWare/pre_config
tags: pre_config
- name: Opérations post install
hosts: '{{ Host_Name }}'
gather_facts: no
roles:
- roles/VMWare/post_install
tags: post_install
- name: Ajout du pointeur DNS sur le controleur de domaine wpsrvctldom1.uem.lan
hosts: DNS
gather_facts: no
roles:
- roles/DNS/
tags: DNS
- name: Ajout du mot de passe Keepass de l'utilisateur root de la machine
hosts: DNS
gather_facts: no
roles:
- roles/Keepass/
tags: keepass
I launch this playbook with this command :
ansible-playbook playbook/deployVM.yml --extra-vars "Host_Name=toto"
My variable is correctly interpreted in my tasks name but my third role which use the value of this variable to do operations on the appropriate host is skipped and Ansible says "skipping: no hosts matched".
But when I re-launch my playbook with "--tags post_install" to play only this role... It works !
I don't know why when I launch the entire playbook it doesn't work and when I launch just the 3rd role.. It works..
Can someone help me ?
Thx :)
PS : I add my {{ Host_Name }} machine into /etc/ansible/hosts file thanks to the 2nd role :

"PS : I add my {{ Host_Name }} machine into /etc/ansible/hosts file thanks to the 2nd role" does that mean before that 2nd role runs, thetotohostname isn't known to ansible? Because if so, I think you'll need to also useadd_host:to teach the in-memory ansible about the host

Ansible reads the /etc/ansible/hosts or any other inventory file before starting the playbook. It is not read again during(or between) the plays. You are populating the hosts' file during the play and then trying to read in the next play; which will not work. You have to add the dynamically created host using add_host to playbook's in-memory inventory.
If you don't want to explicitly add_host then there is another way to refresh inventory. You have to invoke meta module to refresh inventory before the play which requires the updated inventory.
Example:
- name: Re-read inventory files
meta: refresh_inventory
