Andersen, Mattes, and Reshetikhin defined a Poisson algebra structure on a quotient of the free module generated by homotopy classes of chord diagrams on an oriented surface. We show that the number of terms in the Poisson bracket of two free homotopy classes A and B is equal to the minimum number of intersection points of loops in the classes A and B when A and B are not equal. This generalizes work of Goldman and Chas. In particular, Chas showed that a similar statement does not hold for the Goldman bracket unless one of the classes A or B is simple.
