I think the reason is to give the overlap in the center a more realistic
look..
i.e. it would be constructed like this:
+---+
|vvv|
+----|vvv|----+
|>>>>|vvv|>>>>|
+----|vvv|----+
|vvv|
|vvv|
|vvv|
|vvv|
+---+
(Excuse the bad ASCII art)
Where the >> and VV symbols show the direction of the wood grain. If you
overlap the pieces, the two patterns would overlap causing visible
speckling artifacts. If you want it as just a single piece of wood, then
you can get away with just creating a union of two boxes. (or merge, if
you intend it to be a transparent material...)
