That's mostly true Croga.
Basically the SVN in an online storage.
The developer just drops the newest files into their folder, right clicks it and hits Commit.
The online storage (aka Trunk) files are then updated, and a new "Revision" is listed.
The revision is basically the version, but covers the whole svn trunk, instead of a single file.
Now for the users:
When you get the SVN you download the latest files (which means your folder has the latest "Revision/version")
To make sure you have the latest version, even if 1 single file got updated, you just Right-click and click Update.
The folder on your computer will not automatically update itself, but to make sure you have the newest revision(version) all you have to do is click "update".
This will save lots of time for the developers, being that they don't have to rename anything, or create a new .zip file and upload it on the forums, etc...
It will put the user's mind at-ease when they click update and they see they are at, or are getting, the newest files
