Tbh, that picture you posted imo is the misleading one. It does look very severely sloped in your pic, I don’t know why. But trust me, the pic of my bike is exactly what it looks like in person, along with the measurements I gave you of the difference of the top tube heights.
I don’t quite understand your concern or question… yes, the Vanyar design is different than the Eglath, and the Falath, etc.
