New Safari goes back to the link you came from?

I was just reading a couple of stories on here and was wondering what was going on. I kept finding myself not where I expected when I went back to the main page. I am pretty sure, but I had to check three times - you now go back to the link you came from - just like most Windows screen readers. this is great news, as it was one of the things I really disliked about using a mac.
