not sure I understand why would these 2 be None?

I copied it from Cast. My guess is that minor adjustments were needed for types like bfloat16 because of the numpy doesn't support this type, so the numpy values have a different type from the intended type (so, the call to expect is different here, and the intended-type is explicitly mentioned).

Description
Introduces an operator CastLike(X,Y) that casts X to the same type as Y.
Motivation and Context
A common use-case in the definition of function-bodies is to produce a constant, like 0.5 or 1, of the same type/precision as an input Y. This enables such functionality (without requiring the use of a type-context and a context-dependent-function). This will also be useful in defining similar functions that are stored in a model (aka model-local functions).
