The late-stage phase ordering, in d=2 dimensions, of symmetric fluid mixtur
es violates dynamical scaling. We show however that, even at 50/50 volume f
ractions, if an asymmetric droplet morphology is initially present then thi
s sustains itself, throughout the viscous hydrodynamic regime, by a "coales
cence-induced coalescence" mechanism. Scaling is recovered ( with length sc
ale l similar tot, as in d=3). The crossover to the inertial hydrodynamic r
egime is delayed even longer than in d=3; on entering it, full symmetry is
finally restored and we nd l similar tot(2/3), regardless of the initial st
ate.
