We clarify the relation between the model and the convergence results of Jadbabaie et al. to those of Bertsekas et al. We show that the update equations in Jadbabaie et al. are a special case of those in Bertsekas et al. Furthermore, the main convergence results in Sections II and III of Jadbabaie et al. are essentially the same as those derived earlier in Bertsekas et al.
