Val also used an upside-down W-diagram with the two worlds at the top and the four beliefs at the bottom, to emphasize the idea that the world is there first, and is fixed, and we have only a choice of what to believe within a fixed world, not a choice of which background world to live in.

I don't know what a "W-diagram" is (and a simple Google search didn't help), so I don't see how this works. Perhaps a picture could help explain.

I don't know either, but I observe that an upside down W resembles a segment of a conditional tree with two points at the top and either three or four at the bottom, which sounds similar to what the OP is describing.

... an M...?

Why yes! Also a sigma on it's side.

I found the above two comments particularly funny because I had just spent the last couple minutes reading this with the vague feeling that "an upside-down W" would be better described as some other letter but I had been continuously procrastinating actually figuring out what that letter was.

Ah, I think I see it. So on top it has the possible worlds, and on the bottom each world branches into the possible consequences in that world of having each of the possible beliefs.

Yep.
