Pay for set up the twitter on muti-users site

1: I have a multi-user community, I will allow all user to add a "Non-authenticated account" to their own user account.
2: I am showing the default views "tweets" within all user's account page( I am using the APK for user page)
3: Within the arguments section, I choose the
a: "Twitter: Twitter message login name author"
b: Within the "Action to take if argument is not present", I choose the " Display all values"
c: the "Validator" I choose "User", then "Allow both numeric UIDs and string usernames"

the rest I just left the same with the original view.

What I get at the moment is :

1: the same Tweets displaying in all user account with mix all user's tweets, the view doesn't separate by different user ,

Can anybody tell me how should I set this up ? Pay for the advise!!

Waitting for the reply !!!
