To be fair, he's basically under the impression that the dispute between the two groups is about things like milad etc as he's mentioned there. He's essentially as un-versed in the issues as any non desi is including the Arab ulema. That's not an issue specific to him. I mean, how many modern day non desi scholars actually understand the deobandi issue despite often having barelwi students? In any case, the actual issue with Murad is the perennialism stuff, not whether he thinks deobandis are sunni even if they don't practice milad, etc.
