Summary: We give a new proof of the identity $$\zeta (\{2,1\}^l)=\zeta (\{3\}^l)$$ of the multiple zeta values, where $$l=1,2,\dots$$, using generating functions of the underlying generalized polylogarithms. In the course of study we arrive at (hypergeometric) polynomials satisfying 3-term recurrence relations, whose properties we examine and compare with analogous ones of polynomials originated from an (ex-)conjectural identity of Borwein, Bradley and Broadhurst [J. M. Borwein et al., Electron. J. Comb. 4, No. 2, Research paper R5, 19 p. (1997; Zbl 0884.40004)].
