The way you are describing it sounds like they are changing a copyright
notice to an attribution.  Not the same thing.  Attributions are more or
less a courtesy (so downstream users may decide to remove them
altogether).  Batch processing does not remove a copyright.

They can't claim copyright for years previous to any contributions of
theirs.

They can claim copyright for portions they wrote.  The copyright notice
would then read

Copyright (c) 2002-2008 Mike Jervis
Copyright (c) 2008 Gully wiz

They may add other qualifications, like

Portions of this file were created by processing material
Copyright (c) 2002-2008 Mike Jervis

Something like that.  They should write stuff in a manner that makes it
clear that your copyright is still valid on the current code.
