I think it's simpler than that. My bet is that sharp leading edges simply don't have a strong tendency toward pitch instability, so there isn't anything for a reflexed trailing edge to compensate for. A sharp leading edge probably causes stall to occur at a lower angle of attack than a blunt leading edge, and could well cause a separation bubble near the leading edge at fairly low angles of attack. I don't think either of these things usually causes significant pitch instability. I think that concerns about some evil sharp leading edge voodoo are generally without basis.
