The IP address I have last logged for the 7970 ID does not match the above one. This is not to say this his IP address hasn't changed since then due to moving to a new location, but it is looking like this is an impersonator that may have jumped on his name while he had it changed.
I also have an older record of the IP address for 27526 (older than the one above), which is 173.209.109.106. He probably has a dynamic IP address.
