Why are there two patches with identical names and slightly different file sizes?

The lesser one (4MB) is an executable file, and the bigger one (3.2GB) is a package of files necessary for the update. You need both if you want to update your game from vrsion 1.4.4 to 2.2.2.f.
That's weird. Because they're so small I would have thought that they'd be in a single file. Well, thanks.
