Distinctness conjecture for the tori Θsn\Theta^n_s

From papers

Let s,si(1/2,1)s,s_i\in(1/2,1), let kik_i be positive even integers for i=1,,li=1,\dots,l, and assume n=ikin=\sum_i k_i. Consider the Lagrangian tori Θsn\Theta^n_s and Θs1k1××Θslkl\Theta^{k_1}_{s_1}\times\cdots\times\Theta^{k_l}_{s_l} in (CP1)n(\mathbb{C}P^1)^n. Distinctness conjecture. The torus Θsn\Theta^n_s is not symplectomorphic to Θs1k1××Θslkl\Theta^{k_1}_{s_1}\times\cdots\times\Theta^{k_l}_{s_l} unless l=1l=1 and s1=ss_1=s. The conjecture is motivated by comparing counts of minimal-area Maslov-index-2 holomorphic disks and is intended to establish that these tori are distinct up to symplectomorphism, although the supplied text does not state whether it has been proved.
