I see it as an analogy with how, in maths, to fully understand a complicated concept you must be able to explain it using more and more basic definitions, but that does not mean you have to express everything in basis to fundamental axioms, just that you could. Maybe explaining a complex concept in simple terms would take you 2 hours, 12 hours or 3 days, but you can do it if you really understand it.
