Rear cladding spoiler?

[Subix]

I don't really know what to call this but found one similar thread linking to an eBay ad but does anyone know the story behind the cladding with flap/spoiler? Was this to distinguish L/LS models from LSi kind of like the Dodge Stealth did with their base model and wrapped the entire car with that hideous molding to clearly set the few apart? ... or was it actually intended to add a bit of flare design to it all?
