Sasuke was under the assumption with assumption being the key word, he ends up wrong when we find out about Urashiki and later Isshiki and the fact that all Clan members run in two's. She knew they would all come for her and she was correct. She believed herself along with some fodder(white zetsu army) could defeat them. Otherwise she would have tried to get some more allies against them(her own sons for example).
