Sorta.. They're saying I think that to build a wheel that can take the pressures they feel their wheels will need to accept for any rider up to 240lbs, they would have had to add enough weight that the tubeless benefit goes away.
Zipp otoh, has some (IMO) some screwy PSI inflation recommendations that I'd guess are only what they are because their rim couldn't take any more. Eg. a 240lb rider + bike (260lb total weight) gets a result of 70 psi for a 28mm tire, and 73psi seems to the highest PSI that these rims are rated to be able to handle.
