We investigate the finite-temperature properties of the $S$=1/2Shastry-Sutherland Heisenberg model using a quantum typicality method. In theintermediate plaquette state region, we naturally expect to realize thefinite-temperature phase transition associated with breaking the mirrorsymmetry of this model. We reveal some signatures of the spontaneous phasetransition within a two-point correlation level at moderate temperatures sincethe constructed typical state can sense the existence of the degeneratedexcited states depending on the initial random state. We also confirm that thelocal mirror order parameter shows the intriguing recovering phenomenon of themirror symmetry in very low-temperatures, which could be understood from thenature of the ground and excited states of the finite-size systems. We expectthat this recovering feature disappears; instead, a saturated behavior appearsin the local mirror order parameter in the thermodynamic limit. We discuss therelationship to the recent experimental results on ${\rm SrCu_2(BO_3)_2}$ underhigh pressures.
