I think Kuma's ability is more general. He seems to not know for sure where he is sending the people but the type of place and direction. When he sent Perona he asked her a general where she would like to go and it sent. After he has finally sent someone he may then know for sure or just directionally where they go, based on what Sentomaru mentions to Luffy. This is further seen when Rayleigh shows up on Amazon Lily and mentions that he figured it out based on what direction Kuma says that Luffy was sent.
