The authors are locating errors in the proofs of two theorems presented by \textit{H. Niki, T. Kohno} and \textit{M. Morimoto} [ibid. 219, No.~1, 59--71 (2008; Zbl 1158.65023)]. Two counterexamples are used to illustrate the existence of these errors. A new proof is presented for the first of these two theorems and a correct proof from the bibliography is proposed for the second one.
