When Obi-Wan lost his saber in EpI against Darth Maul he didn't keep the one from Qui-Gon. In epII we see him with its own rebuilt from scratch. Kyle probably did the same and in facts in Mots he has an orange saber.
After his failure as a Jedi he probably throwed away his orange one and started to train as a student at the academy with a new blue lightsaber, the one he left to Luke after deciding he would never be a good Jedi.
That's just a theory
