There is no contradiction there. Current is not power. Power is voltage
times current. Since the impedance of a short antenna is not the same as
the impedance of a larger antenna, it makes perfect sense that the current
for a given power level will not be the same.

Feed 1kW into your 472kHz antenna and get only 1W erp, most of
the high current driving the ohmic resistance and not the radiation
resistance
