My answer was only looking at the mere numbers and factoring in the main principle that, considering the noise floor of any amplification stage, loading it in its optimal zone will improve the S/N signal to noise ratio.
Thus there is no fundamental contradiction, so to speak, KAB targets a lower preamp input voltage, hence recommends less gain.
It could very well be that KAB reached the conclusion that the sweet spot of preamps input is less than 500mV? Don't know, I tackled this from the numbers angle only.
Many preamps indicate that they handle overloads very well, over the specified 500mV and harvest better S/N ratio in the process.
