The authors are concerned with the randomized double block Kaczmarz method developed for inconsistent linear systems by \textit{D. Needell} et al. [Linear Algebra Appl. 484, 322--343 (2015; Zbl 1330.65056)]. They shorten the original convergence proof and show that the method converges for any proper initial condition.
