[Harry Potter] When did Snape intend to drop his double agent guise?

As late as mid-way through the battle of Hogwarts Snape was still deeply undercover and an advisor to Voldemort. When did he expect to turn heel fully? 

In the forbidden forest? In the courtyard? Only after Nagini died? It would look awful suspicious to reveal good intentions after Voldemort died without his direct intervention.

It seems to me that the mission was only to be over once Voldemort was truly defeated. I’m assuming he had some sort of insurance to prove he was good if he survived until then. Of course, it’s entirely possible that he fully intended to go into exile or even simply go to Azkaban once the war was over. It’s even possible that he intended to sacrifice himself in some way before it was all over.
