I think his idea on the change is the same reason why I use my real first name (Chris.) After you reach a certain age you should get tired of someone calling you a name you make up for yourself on the internet...it starts off as stuff like "SSJ Goku x9" to something else you make up like..."Viper Snake <year your were born here>" to like something more plain that you think sounds cool like "Tseng" (although I think he got that name from a character in FF7...Tseng's previous account "SaitoHajime" is a kenshin character =P) to your real name cause you start to feel awkward.
