This is not a substitute/equivalent for placing a workpage in two or more categories. This places a workpage not just in another composer category, but in a specific "subfolder" - the Pasticcios subfolder/tab - of that category. If the workpage isn't a Pasticcios page, don't use template PasticcioCat, just use "Category". Also:
format--
PasticcioCat firstname(field) | lastname (not lastname | firstname).
