Can you detail further what you mean? My understanding is similar to this article. They didn't think that the Jim crow laws went far enough, so they ultimately based their treatment of Jews more around the US treatment of natives (eventually also mirroring the US with an extermination attempt)

They weren't nearly as strict as the US on racial purity though, which might be what you're referring to? In the US, one drop of black blood would qualify you as legally black. In Germany you needed three Jewish grandparents to be classified as a jew. That's significantly more lenient than the US.
