I am not quite sure what you mean by "why"? The "mechanism" or "what is
the use of it"?
As to the former: GraphicsArray has a DisplayFunction option which is
separate from the one in Graphics, so you can set them independently.
For example by setting
SetOptions[GraphicsArray, DisplayFunction -> Identity];
you can produce the opposite effect to the one in your example:
plot = Plot[x^2, {x, -1, 1}]
draws a picture but
Show[GraphicsArray[{plot,plot}]]
GraphicsArray
produces no picture. That seems to me all one can say about the
mechanism. If, one the other hand, by "why" you mean "what is the use
of it", well it seems to me that this is obviously the more flexible
approach compared to having just GraphicsArray inherit its
DisplayFunction setting.
