Entries like this become confusing when a user is renamed. The subject of the above sentence is stored as a number (his user id 55217) but the direct object is stored as text (log_title == "Dbiv" && log_namespace == "2"). This is the name of the target page/user at the time the action was taken.
One part of the data reflects the name change, as viewing the log looks up the new name based on the user_id number which remains the same, but old data is used for second part.
In effect it becomes less obvious that he unblocked himself, which is usually considered the highest form of admin abuse. This is inherently more serious than whatever was done to warrant the block, whether it was justified or not.
