The problem is:

Great Jaggi =/= Cheetah =/= Lion

There are also evidence against it.

The double Great Jaggi quest explicitly says that it's a territorial fight so this is out. The four Great Jaggis in the Event quest always appear after each other so you can't see any cooperation there, too.

Lions maybe, but I know that Cheetahs only hunt in pairs with their partners though there is recently found a group of 3 brothers that hunt together. And that's till now only a very rare occurance.
