In a Latimer diagram for sulfur in basic solution, the species S2O3^2- (thiosulfate) is unstable with respect to disproportionation. This is because its reduction potential is higher than that of SO3^2- (sulfite) and lower than that of S(s). Therefore, it can undergo both oxidation and reduction reactions, leading to the formation of a mixture of sulfite and sulfur.
