Rules regarding naming conventions got changed several times in past years.
The character you mention is older then the latest rules. So it is ok that he has that name.
Additional FYI: Once a handle has been accepted, it's legal either way. The owner of the handle can choose to have it changed for breaking the rules if they wish (as per the recent Sim News) but they are never forced to do so. This also applies to handles predating the current rules.
