Like I said. Different circumstances. Anyway Sabo had plenty of reasons to change his name whether it be shame of his family(that wouldn't make the slightest protest when their 10 year old was murdered), protecting Luffy and Ace who were targetted by Sabo's parents and might have been put in more danger with news of him becoming a revolutionary, or maybe the big boom knocked some screws loose and he honestly doesn't know his identity.
