Absolutely correct. The cows remain 100. When I said buy 200 cows back, I meant by the 100 cows TWICE. Buy them, give them back to the second person you borrowed them from, then buy them again, and give them back to the person you borrowed them from originally. Sorry for making it confusing in my attempt to simplify it.
