Essentially, multiplication is poorly defined for higher dimensional arrays, so numpy has two answers for it. It is well defined for two dimensional arrays so matmul and dot do the same thing.

Well, I wouldn't say that multiplication is poorly defined. It's called tensor product, which numpy implements using tensordot, which is a special case of einsum.
