sync*/async/async* generators have two parts: an entry, which does checks and computes the element type of the result, and a body, which is transformed after lowering to JavaScript. The split ensures that the code for checks is done at function call time, rather than e.g. in the moveNext method of a sync* iterator. A following CL with optimize the split to generate one function when there are no checks and the type argument is simple enough for textual substitution.
