This is done by design and has been explained too many times to count.
The emails used for the client during signup are never deleted completely. They get 'marked' deleted and kept for a few reasons. One being so spammers can not reuse the email to create new accounts. Another is so that you have a record of all the clients you have had on your server.
Sentora does this with many other things too. (Marks them as deleted instead of full delete.)
If, like me, you do a lot of testing and things, I made a module that allows you to clean out this saved information.
It's called the 'Deleted Records Manager'. Install that and you can delete testing records or accounts as needed.
