The insert shot does the job I suppose, however I still despise the attitude Obi-Wan is giving Anakin. He is basically blaming Anakin for wanting to win their training duel, but behaves like a child that lost a game and insist on playing on until they have won themself.
It’s implied by Obi-Wan’s dialogue before the duel that Anakin usually won their spars, so him winning another wouldn’t have proven much. I took the speech as him saying that Anakin was getting too pre-occupied with winning or losing their spars and that he should have treated it as more of a learning opportunity. The interpretation that Obi-Wan is supposed to come across as a bit overbearing to give justification to Anakin’s rants also works. I’m fine with the live-action movies showing a more antagonistic side of their relationship when the animated stuff does plenty to show them being friendly with each other.
