solid router's Data API

I'm a little bit confused about createAsync with the load function
In the example of the GitHub repo, there's a cache fn to fetch data

const getUser = cache((id) => {
  return (await fetch(`/api/users${id}`)).json()
}, "users")


Then we attached it to the load function of the Route

import { lazy } from "solid-js";
import { Route } from "@solidjs/router";
import { getUser } from ... // the cache function

const User = lazy(() => import("./pages/users/[id].js"));

// load function
function loadUser({params, location}) {
  void getUser(params.id)
}

// Pass it in the route definition
<Route path="/users/:id" component={User} load={loadUser} />;


Then in the current route component, we have to again attach the fetch function to the create async

// pages/users/[id].js
import { getUser } from ... // the cache function

export default function User(props) {
  const user = createAsync(() => getUser(props.params.id));
  return <h1>{user().name}</h1>;
}


Then why can't we just attach to the create async only? Why are we attaching the function to both Route's load fn and create async? This kinda confused me
