20x100kb = 2mb - 20 generated host maps are simultaneously uploaded to the server;
20x100kb = 2mb - 20 generated maps are simultaneously downloaded from the server to the joining player.
I would interpret it that way.
You can check the size of the created maps for HL+U in the maps/random maps/ directory; the generated map files are stored there.
