I don’t think Nintendo would have a case against Valve, only against the developers of the demake.
It looks more like Valve wants to maintain a good relationship with Nintendo, given Valve has ported Portal to the Switch and may intend to port more of their back catalog.
Some people are also saying valve gave the guy a friendly warning about using the Nintendo sdk rather than sending a cease and desist, and the reporting on it was misleading
