Maybe you can reduce code/task duplication with the following idea:

---
- hosts: localhost
  connection: local
  gather_facts: false
  vars:
    - data:
        - name: row1
          roles:
            - role1
            - role2
        - name: row2
          role: roleA
  tasks:
    - debug:
        msg:
          - "{{ item.1 if item.1 is defined else item.role }}"
      loop: "{{ (data | selectattr('role', 'defined')) + (data | subelements(['roles'], skip_missing=true)) }}"
...

Yes, that makes sense and it should work. I'll look at implementing another change here
