I noticed (and reported) the same bad link. Shame it's still a bad link.
It appears that the Help Files for some other CS 6 programs, are still missing, broken, or leading to previous versions. Not sure what happened (rolling out the Creative Cloud too?), but things are not working, as they should. The Help Files have been a big bone of contention on the Photoshop Forum, as well, and I am not sure if that has been resolved yet.
