Considering that diffusers need distance to avoid frequency lobing and comb filtering (less of problem than lobing) that's not a good recommendation that way I see it. I also very much disagree that one shouldn't use treatment on the wall behind the speakers.I have a recommendation from an acoustician that I should use all diffusers and no absorbers due to the unique nature of omnidirectional speakers. I was also instructed not to use any treatment on the wall behind or in between the speakers.
Type of treatment will depend on proximity to surfaces in relation to speakers and the listening position, how much the treatment can build out, budget and design goal. But generally, diffusion alone in such a small room wouldn't work very well IMO. Diffusion requires more distance. A combination would be better. And avoid simple scattering units that will not diffuse the sound evenly.
