Pretty much that. Basically the northern hemisphere can’t work because bathtubs, but a lemon squeezer where the middle bit is pretty close to a hemisphere does work because science changes depending on viewpoint.Water conforms to the shape of the container it is in like a bath. Always finds its level so can't possibly curve.
But he says because there's an ice dome that means its in a container so the lemon squeezer model works because it's enclosed and has steps in the ocean. Keep up man.
