Just did a quick dig, the confusion was arisen by Sean Murphy, who was (not sure if still is because of Lisa's existence) outsource manager. He mistook the Surveyor (the art of which actually became the Carrack instead of the Reclaimer) for the Collector which was the old Vanduul Harvester Carrier, which based upon the recent leak is now named the Driller.
Long story short, apparently the whole naming the Reclaimer the Surveyor was just a clusterfuck of accidental confusions.
