Maybe it is not a good example of rhizomatic learning?
I understand this sort of stuff with reference to the original writings of Deleuze and Guattari about rhizomatic thinking. For me, that's about the way that things that are seemingly different (heterogenous) things can become connected in my mind and then lead me to have new ideas. So rhizomatic learning would be the way that things you read and talk about help you to understand old things in new ways, and look at the world differently. I guess if I was summarising this right now I'd say it's about connecting things differently.
I'm not sure if that helps or not.
