As I read it, it seems to be saying that our brains are multi-threaded, but not multi-core or multi-processor.
The lower priority 'threads' which are not the intended focus still do take cycles in brief moments when the main task is idle only to be preemptively interrupted at the cost of many context switches and adding very little value. The same happens with hardware CPUs which is why coroutines are much more effective when the number of tasks >> number of processing units.
