Even if the new secret keeper isn't Snape, the OoTP would not go back as Snape still knows about the old location, and now based on their latest info, he's on the Dark Side, so he's still a threat to them.
I think even if Snape knows the old location, he can't inform others as he is not the secret keeper....
Remember Dumbledore told Harry at the end of book 5 that Kreacher was not able to inform Malfoys' about the head quaters as he was not the secret keeper....
Anyways the whole concept is confusing..........
