while iWhile I do think that it was some poor planning, iI think there is a reason for it. theThe reason iI would suggest would be that they are all portrayed in their most moral and just form. obiObi-wanWan by that time had reached his ripe age, had patientspatience and was very Jedi like. sameSame for yodaYoda. iI would go as far to say that it is showing the characters in their most pure form of being JedisJedi.
