you can do
return result
.catch(e => makeThrowingMatcher(matcher, isNot, e).apply(null, args))
.then(() => Promise.reject(
// new JestAssertionError(...
));And drop the async

Wait no, that won't work either. You have to use .then(resolvedHandler, rejectedHandler) to avoid handling the rejection here.
So just move your catch into the second argument of the then.

Is there any difference between A and B, besides syntax preference? Both a and b pass the test cases.

In this case, yes. since we expect it to fail we need to have our catch first so we can resolve the promise with it. But if it does not reject we need to reject it ourselves.
If we add a then after the catch, it's not called. If we add our catch onto a then, we locally catch the rejection we want to bubble up
