The anti-correlated behaviour of these two networks, and even their default mode vs. attention functions, reminds of the attention schema theory of consciousness [1].
Specifically, the attention schema theory posits that some constant back and forth signal switching between internal and external models of the world results in the illusion of subjective awareness, in an analogous manner to how task switching provides the illusion of parallelism on single-core CPUs.
