Optimal seatings changes

Because right now the three games goes like this:
game 1: A is prey of B
game 2: B is prey of A
game 3: A is grand prey of B

I think it would be better as:
game 1: A is prey of B
game 2: B is grand prey of A
game 3: A is grand prey of B

...if possible.

Round 1
1,2,3,4,5
6,7,8,9,10
Round 2
10,1,9,8,2
5,6,4,3,7
Round 3
4,7,10,3,1
9,2,5,8,6

If on round 2 players 1 and 9 would change places, would it break it?
