  We study numerically the chromoelectric-chromomagnetic asymmetry of the
dimension two $A^2$ gluon condensate as well as the transverse and longitudinal
gluon propagators at $T>T_c$ in the Landau-gauge $SU(2)$ lattice gauge theory
with a particular emphasis on finite-volume effects. We show that previously
found so called symmetric point at which asymmetry changes sign is an artifact
of the finite volume effects. We find that with increasing temperature the
asymmetry decreases approaching zero value from above in agreement with
perturbative result. Instead of the asymmetry we suggest the ratio of the
transverse to longitudinal propagator taken at zero momentum as an indicator of
the boundary of the postconfinement domain and find it at $T \simeq 1.7 T_c$.
