The exporter scripts have nothing to do with loading Poser content - D|S can do that from the base installation. However, not all material settings are read and sometimes an item will be so dependent on the missing settings that it will look very odd after importing (though often you can redo the settings in D|S to get the same result, if you know how). Sometimes rigging or elaborate multiple scaling and morph relationships don't work in D|S as they do in Poser, requiring a D|S specific version (if possible). And sometimes an oddity in the library file will cause problems for D|S but not Poser (or vice-versa, of course).
