These are different objects. A height_is is *not* represented as a mesh, it
is just traced as if it were a mesh. In particular note that the
documentation says a height field is solid, not a finite patch.

Because it is a finite solid, not a finite patch. I am pretty sure the
documentation somewhere says that a height field is a solid and explains the
plane below. Either way, the purpose is the use in CSG.
