I'm still a little confused as to what you're looking for.
When the user clicks any of the social network login buttons, they will *have* to authenticate with those networks. That requires redirecting them to the social network to verify their credentials. Some social networks, like Facebook, can automatically redirect them back to your site if they are already logged into Facebook and have previously used Facebook to login to your site. Other networks may still show an approval prompt to verify the user wants to login.
With the Automatic Registration feature enabled and the User Redirection settings as "Same Page", the user should be brought back to the same page they were on before they tried to authenticate. They should not be redirected to a different page.
I hope that helps explain. If not, again, please let me know specifically how you are testing (what you are doing), what you expect and what is actually happening.
Thanks,
Alex
