Sorry, but if you'll read it again you'll see that it says the load limit for various inflation pressures. I think that means for a given inflation pressure, that's the maximum load carrying capacity.
Two ways of saying the exactly the same thing. Maximum load for a given pressure has exactly the same practical meaning as minimum pressure for a given load. The chart then has the note that the tire engineer can increase the pressure up to max psi without increasing the load and this difference is what the engineer has to work with when determining recommended pressure. ie, NVH vs performance, which usually means leaning towards soft and squishy so john Q public does not feel or hear the road.

Please note they call it recommended pressure not required pressure, or some such, because there is no safety issue in going above the recommended pressure. If there was you can bet the NSHTA would have long ago had a placard with that in big bold letters. In fact it could well be that higher than recommended pressure is safer as it gives more crisp steering response and better cornering traction. We already know for a fact that higher pressure means better hydroplaning resistance.
