Delegate to localhost does not change inventory_hostname, if it did it would
break a lot of code out there.
And I can prove it with this code that mimic you codes behavior.
$ more test.yml
---
- hosts: a1,a2
gather_facts: no
become: no
vars:
myvar:
- value1
- value2
- value3
tasks:
- lineinfile:
path: /tmp/test
line: "{{ inventory_hostname }} {{ item }}"
insertafter: EOF
create: true
delegate_to: localhost
when: item == "value2"
with_items: "{{ myvar }}"
And by running it I get
$ ansible-playbook test.yml; echo "Content of /tmp/test:"; cat /tmp/test
