Uniqueness of a tropical variety from its tropical Chow hypersurface

Let Σ1,Σ2Rn+1/R\Sigma_1,\Sigma_2\subset\mathbb{R}^{n+1}/\mathbb{R} be pure (nk1)(n-k-1)-dimensional tropical varieties. For a tropical variety Σ\Sigma, let ZΣZ_\Sigma denote its tropical Chow hypersurface. Tropical Chow uniqueness conjecture. If

ZΣ1=ZΣ2,Z_{\Sigma_1}=Z_{\Sigma_2},

then

Σ1=Σ2.\Sigma_1=\Sigma_2.

This assertion is false when the equality is interpreted as equality of sets rather than equality of tropical varieties, so the conjecture is refuted in its set-theoretic form.
