You could remove the link line.
I have never seen an implementation using [last.name], [first.name] as unique key contact.name. In big organizations there's always the possibility to have duplicates.
In actual system I work on (using AssetCenter as leading system for contacts) both - operator name and contact.name are identical - this helps integrating both data. Maybe in a new release HP architects change it
In such an environment (operator name=contact.name) you could create a link line for field "name" that fills "name" from "contact.name" and that fills variables called $L.xyz.first.name, $L.xyz.last.name from "first.name" and "last.name"
and in post expressions (link details) you create an expression like:
full.name in $File=nullsub($L.xyz.last.name, "")+", "+nullsub($L.xyz.first.name)
cleanup($L.xyz.last.name);cleanup($L.xyz.first.nam e)
