They are sort of redirecting. Redirecting usually means that your site has a message that tells a browser to go to another site. What FR is doing is somewhat different. They actually changed their IP address in the DNS system.
This is dumb because even though it looks like google, it isn't and it doesn't actually work. Click the groups link and you will see that it doesn't work.
So they compunded what sort of looks like theft, with something that looks like theft done incompetantly.
