Well, one reason that gnuplot doesn't recognize that construct as an 
area is that, except in rather special cases, that _is_no_area_.  A 
closed polyline in 3D is usually just that: a closed polyline.

The way splot recognizes surfaces is described in the documentation.  In 
a nutshell: instead of

A
B
C
D
A

E
F
G
H
I

you should have

A
B

D
C


E
F

H
G
