This appears to be degenerate perturbation theory. There are two benzene states |a> and |b> with the same unperturbed energy E_0. There is a small perturbation V that connects the states, with A=. Thus, "the easier the flipping back and forth between the two states, the higher the coefficient A". This gives a 2X2 matrix |E_0 A | | A E_0|. The perturbed energies are obtained by diagnolizing this matrix, resulting in energies E_1=E_0+A and E_2=E_0-A. Thus, "the higher the coefficient A, the higher the energy separation between the two states."
