Firstly you should have a look at the delegate_to which might be a better
way at achieving what you want. But I am assuming there is a good reason
for your current approach. The reason it does not work is that the limit is
still in place after you have done an add_host. So when it gets to the
second play it see that there are no hosts both in temp_group and group1
and will therefore not do anything. One solution is to add temp_group to
your limit. So you would run "ansible-playbook playbook.yml --limit
group1:temp_group".
