Who is even allowed to create news with this combination?
It makes perfect sense to me, that only this person is able to edit it 
afterwards (or other users with similar permissions).

I don't think thats possible and imho it doesn't make sense, because 
usergroup1 could just remove the categories of usergroup2 in a news entry.

What you could do is have a folder structure like this:

news
- usergroup1-news
- usergroup2-news

In your usergroups remove all categories.
Then let the usergroups only store news in their folders (no matter what 
categories) based on the typo3 permissions for the folders.
Then configure tt_news to recursively read all news from the "news" folder.

Of course you now still have the problem, that users then can create news 
tagged with the other usergroups categories.

You might also have a look at the 'news' extension (not tt_news).

cheers
Christoph
