More claification:
- the user signs up using a custom sign up form and is created using 
wp_create_user function.
- user then exists in local site user list, and mulit-site user list
- local admin for that site then deletes that user, however user still 
exists in the network user list
- the user then tries to sign up again at a later date, however now 
username_exists function will return true because username exists in 
network admin list, but not in local website

Thanks.
