Very true. But it also says not to lube it here:

Specifically he tells us not to lube the auto hub. This is in the PDF version of his assembly manual as well.
From the two pieces of information, I think he means it should not be lubed to avoid the 'wah-wahs', unless you have the auto hub sticking issue, in which case he recommends lubing with tri-flow.
