(Spoiler) Sandor Clegane

I keep seeing people who are pretty certain this guy is alive and a holy man now. And I can see from a lot of ambiguous phrasing how one can have that conclusion. But the Elder Brother on the Quiet Isle says,

"I buried him myself. I can tell you where his grave lies, if you wish. I covered him with stones to keep the carrion eaters from digging up his flesh..."

That seems pretty straight forward that his body was buried. Help me out?
