Not sure if I understood the question but it seems like a circular permutation question.
Total arrangements =(n-1)! = (7-1)! = 720

Yes. This is a circular permutation.

Answer should be (7-1)! = 720

Indeed this is a confusing question. does it ask to find arrangements in a circular arrangement or arrangement where the second arrangement wont have the same person seatign next to the same persons and on the same seat......

For circular arrangements no of ways = (n-1)! =6! = 720
