Summary: 
In their paper[1], Sasase and Mori proposed a method of calculating the resequencing delay for a multiple-server queueing system under a threshold-type scheduling. However, it is found that the result of the proposed method does not converge to the corresponding expression in Ref.[2] for the system with two servers. In this correspondence, we show that the proposed method in Ref.[1] is not correct, and verify it by simulation.
