For example at 500 lbs vertical load a tire may provide 700 lbs of available traction.

But the same tire at 2000 lbs vertical load may only provide 1500 lbs of traction.
Yes load in that case refers to cornering load or acceleration/deceleration load. More downforce on the tire would shift this whole curve upwards, but not in a linear way.
