Command line variables not respected in case of an include and variable rename

I have the following scenarion

I have definied a variable named old_var_name inside group_vars/all/common.yml the following way

group_vars/all/common.yml

old_var_name: some_text

I have a foo.yml and a bar.yml files defined the following way:

foo.yml

  • name: Do stuff
    vars:
    new_var_name: “{{ old_var_name }}”
    include: bar.yml

bar.yml

  • name: Debug var
    debug: msg={{ new_var_name}}

If I call the tasks from the command line and try to pass old_var_name with "-e “old_var_name=command_line_text” I expect the result to be:

ok: [ab-linuxbpc-2.sit] => {
“msg”: “command_line_text”
}

but instead I get

ok: [ab-linuxbpc-2.sit] => {
“msg”: “some_text”
}

If I pass "-e “new_var_name=command_line_text” I do get the desired result.
In addition If I move the declaration of old_var_name from group_vars/all/common.yml to the defaults of the role where foo.yml is definied I also get the desired result.
It seems the command line varialbe cannot overwrite just the group one.
Is this expected? Or I should file a bug?
