I'm really no expert but if I understand it correctly the `M/M` part defines the distributions of the arrival and service processes, so this definitely is important as others have already mentioned in the comments. E.g. a D/D/1 queue where D stands for deterministic arrival shouldn't suffer from this problem.
This doesn't change the interesting fact the article presents but throwing in technical terms without proper explanation is imo bad style. Either don't mention it (would be better in this case) or explain it and why it is relevant.
This is also a common "mistake" unexperienced people make when writing papers. They mention a fact that is somehow related but is completely irrelevant to the topic and the rest of the paper. I don't want to assume anything but to me this often smells like showing-off.
