It was a simplified description of how PAE works. The point was that PAE work at the page table level and just remaps memory pages to fit within the virtual 32-bit/4GB address space for a 32-bit process. There are still constraints in PAE on how much memory one single process can use and adding memory to a machine where you use PAE does not automagically solve all your memory bottlenecks.
