if i understand correctly, you are setting my_int_if: eth1 and then
setting my_int_ip: "{{ ansible_eth1.ipv4.address }}" which is always
hardcoded to eth1.
i think what you would want is
in group_vars/all
my_int_if: eth1
and reference it in template and other places via:
bind-address={{ hostvars[inventory_hostname]['ansible_' +
my_int].ipv4.address }}
and in playbook as
host={{ hostvars[item]['ansible_' + my_int].ipv4.address }}
