My interpretation is that fof+hot might not have immediately obvious utility, so that it's made into myth(heuristics?) when it's particularly valuable. For exam

My interpretation is that fof+hot might not have immediately obvious utility, so that it's made into myth(heuristics?) when it's particularly valuable. For example, in fof+fot it wouldn't make any sense to allow yourself to be slapped, because you need a complex casual model to justify it. But echoing others in the thread, I'm not too sure and wish the author had written more on the topic or gave some references.
