This was indeed a very interesting question.. short answer, RAM compression.

Memory that has not been active (and hopefully, doesn't need to be 
often) can be stored in ram in a compressed form, significantly 
increasing the load you can put on a system that doesn't have real swap 
space but limited memory (such as, running the GUI installer, which is 
what ubuntu uses it for)
