UV Mesh. Is there a way to make them automatically overlap perfectly?

Right Now the mesh does not look exactly the same, which frustantes me because I want to overlap them.

I can’t see why its not the same. Since it is the same on the Model side:

(I moved them and scaled a bit, that is not the issue!)

As you can see, the vertecies are not at the same places… Why is that? (It could only be because of rotation?) And how would I fix this?

Right Now I am looking at the “Weld” and “Align” Tool. Is that the best way to solve this?

Wondering same thing. So is there already this function available?
