Is there a reason why the two are not the same?

The "pdf via cairo"-exporter uses sp_item_invoke_print() while the "postscript via cairo"-exporter uses the new CairoRenderer class (the same class as is used for printing).

In extension/init.cpp one can active a "Cairo PDF experimental"-exporter that also uses CairoRenderer.
