In the book Advanced Japanese Grammar Dictionary, I was looking into aruiwa, and it was giving examples of when you can and can't replace it with soretomo. In the example sentences in [1] you can replace it, and in [2] you can't. However, [1] b) and [2] d) are identical. So, can soretomo replace aruiwa here or not?
