In the paper [5], the authors defined the well-structured symmetric switch block M-N,M-W and showed that M-N,M-W is universal for any pair of positive integers N and W, However, we find that this result is partially correct. Here, we show that, when N greater than or equal to 7, M-N,M-W is not universal for odd Ws (greater than or equal to 3) and it is universal for any even W.
