Hm, I am not sure if such a feature is very relevant to Admin Tools. The idea of removing users who have never logged in is that these are usually spammer registrations you don't want to keep.
In your case, those never logged in users will be deleted. Since the accounts are created by the administrator they are activated, but if the user never logs in then Admin Tools will delete them, unless you select a different option.
