It is unclear if "access to this information" means specifically "access to the admin panel" or "access to all personal information". It could still be possible for Roger to access personal information without access to the admin panel depending on blockchain.info's network and database security.
Roger has never had access to the database, backups or any server access. He now has no elevated privileges over normal users.
Thank you. This is satisfactory and I will remove all my posts and signature related to this. I hope my trust in you is not misplaced. I respect you, your business, your contributions to bitcoin, and your quick and responsible response to this event.
