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.
