Nowhere does that say same, like you're trying to force.
It makes sense you'd resist and twist what I'm saying, because it means people like you are literally part of the problem.
Since you edited your post, I'll respond:

They are still undeniably two separate parties that both inherit the most important traits from the root problem of dominating capital interests.
https://en.wikipedia.org/wiki/Uniparty
> Uniparty is a political term referring to the idea that seemingly separate political parties, typically the two dominant parties in a liberal democracy, function in practice as a single entity. It is often applied to the Republican Party and the Democratic Party in the United States, or to the Conservative Party and the Labour Party in the United Kingdom.[1] The concept implies that despite their outward disagreements, the parties collaborate behind closed doors and share a unified set of political and economic interests, effectively creating a de facto one-party state. Proponents of this idea argue that such a "uniparty" suppresses genuine political alternatives and dissenting viewpoints by exercising control over the media, grassroots organisations, and ballot access regulations.[2]
