We demonstrate that in the ballistic limit ($D\\simeq 1$), the crossover between the quasistationary evolution of the Josephson phase difference $\\varphi$ at small voltages and transport by multiple Andreev reflections at larger voltages can be described as the Landau-Zener transition induced by finite reflection in the channel.
