That doesn't prevent them from deleting their attachments just from editing the post and manually removing them. Attachments can be managed in the UCP and deleted regardless of that permission.
@bukkaked, you would need to set group forum permissions so that they could not delete or edit their posts
and you would also need to disable the Manage attachments function in the UCP. Those three things together would prevent users from deleting attachments they uploaded.
