Strictly speaking it does. However it's convenient to have a tuple with more generic compatible afterward. I tried to explain some of the reasoning for that on this email [1]. More in general this tuple of compatible is matching how the actual system is layered (SoC -> base SoM -> SoM variant -> carrier board) that is also reflected on the dtsi include hierarchy. FWIW, this is the standard approach you can see on fsl.yaml, where such kind of modular system are pretty much standard.
