Use *set_fact* when you want to keep the "current" aka "instantiated"
(I'm not sure the wording is correct) value of the variable in
hostvars, e.g.
- set_fact:
testvar02: "{{ testvar02 }}"
- debug:
var: hostvars[ansible_host].testvar02
would give
hostvars[ansible_host].testvar02: 'var_in_role: define in role only'
