It was recently observed in a lattice QCD measurement that the chiral condensate in the quenched approximation shows dramatically different behavior in the three {ital Z}{sub 3}-equivalent deconfined phases. We argue that this phenomenon can be understood qualitatively as an effect of {ital Z}{sub 3} twists on fermionic fields. Quarks under these {ital Z}{sub 3} twists become global anyons and, hence, display different thermodynamic properties. We further show that the lattice data can be roughly modeled by a Nambu{endash}Jona-Lasinio{endash}type Lagrangian with a minimal coupling to a constant gauge field {ital A}{sub 0}=2{pi}{ital nT}/3 (with {ital n}=0, {plus_minus}1), which arises naturally from the nontrivial phase of the Polyakov line. {copyright} {ital 1996 The American Physical Society.}
