Hmm that's a good point, but IMO the distinction isn't sharp enough to make a big deal over. The core idea of SoM as I see it is that human cognition is often quite decentralized, and that any illusion of a unified self is constructed piecemeal from the outputs of smaller, less-aware subsystems. Generally it's expected that the subsystems communicate with each other, yes, but I think "disproportionately rely on one or two members for complex questions but act like you're unified overall" still fits the bill.
