Right. So, he is manipulating the structure of the naturals as a directed set.
His notion of successor treats each successor as a choice function.
So, given some initial segment, any pair of choice function names corresponding to any initial segment of the given initial segment are in relation to the name of the choice function for the given initial segment so as to satisfy the axioms of a directed set.
But, when a choice function name corresponding to any initial segment of the given initial segment is paired with the choice function name of the given initial segment, the selected pair of choice function names do not satisfy the axioms of a directed set as the choice function name of the given initial segment is a greatest element.
Without the equal signs, his choice functions form the collection,
{|({|}),||({|,||}),|||({|,||,|||}),...}
So, what application of a choice function orders his choice functions so that a new choice function can be selected to resolve the problem?
One could apply the same strategy.
Given the new choice functions to account for a well-order of the collection above
