No, he gave up the drive and everything he had from company's IT for review. They are very purposefully avoiding mentioning that, but logically you can't conceive of how they can review the thumb drive without him willingly giving it to them first, nor that he had authorised access to such data in the first place. The charge says nothing about his accessing the data unlawfully, other than saying that he had "no reason" to access it, and it being outside of his immediate responsibility.
