Obito couldn't have taught him about the Rinnegan abilities because Obito never had the Rinnegan before taking it from Nagato... That way makes more sense to me too, but it is odd that he didn't learn any of the Rinnegan's abilities until after Jiraiya left. There's also the fact that Nagato and Konan knew about the Gedō Mazō and that summoning it would be a bad thing. I remember the anime tried to explain this in filler by saying he just summoned it at random one time, but I get the feeling that wasn't Kishimoto's intention. Plus that filler completely ignored Obito being Akatsuki's founder.
