At high temperature the thermal fluctuations destroy the orders; correspondingly the free energy is a smooth function of the physical parameter and the singularity would occur only at complex values of the parameter. Since a complex parameter is unphysical, at high temperature no phase transition is expected with varying the physical parameter.
