Also, what does Step 3, Simplify do?

It does exactly what it says, it attempts to reduce the number of hulls for the physics model.

But with that being said, you do not want to use analyzed physics for a terrain mesh since you'll never get good tracking that way. Analyzed physics also tends to end up as much heavier than unanalyzed for large irregular meshes like this - another reason for not hitting the Analyze button.

If the terrain is suppsoed to be walkable, you use the high model as the physics, no analyzing or anything else fancy. If it's not supposed to be walkable, use a cube as physics and set the mesh to phantom after you've uploaded it.

A physics model can be created from a LOD for a model.

Not created from, it uses the LOD mkodel you choose directly for the physics. That's not relevant in this case however since the only correct way to handle LOD for a mesh like this is to "use level above" all the way so all four LOD levels are identical.
