How can he have too much amperage available? If the wires two the 120
volt circuit are as big as the wires to the original circuit, and the
receptacle is big enough to handle whatever is plugged in, how can
there be too much amperage?

It's real simple: the electrical code requires that the receptacle's amperage
rating cannot be less than that of the circuit. The only exceptions are that
15A receptacles are permitted on 20A circuits, and receptacles rated less than
15A are permitted on 15A circuits.
