It is shown that the difference between the masses of charged and neutral mesons obtained under the assumption that this ratio is constant on a scale of the order of the beam energy spread can differ from the true one by $\\delta M \\sim 0.03\\,\\mbox{MeV}$ at the energy of $\\Upsilon (5S)$ and by $\\delta M \\sim 0.4\\,\\mbox{MeV}$ at the energy of $\\Upsilon (4S)$.
