There is certainly more to the story behind that root system than is explained in Kempf's narrative.
One key omission in the Kempf narrative is differentiation between seminal and nodal roots.
Most if not all of the roots visible in the pic are nodal roots (as opposed to seminal roots).
this pub provides a good discussion of seminal and nodal corn roots:

and this old publication contains some great illustrations of corn roots at different growth stages.
