Given a family of (W) contractions T1,...,TN on a reflexive Banach space X we discuss unrestricted sequences Trn∘...∘Tr1(x). We show that they converge weakly to a common fixed point, which depends only on x and not on the order of the operators Trn if and only if the weak operator closed semigroups generated by T1,...,TN are right amenable.
