original code in `/lib/router/router.js`
```
urlIsNew (pathname, query) {
return this.pathname !== pathname || !shallowEquals(query, this.query)
}
```
the urlIsNew compare `this.pathname` to an argument `pathname`
the invokers:
```
// If asked to change the current URL we should reload the current page
// (not location.reload() but reload getInitialProps and other Next.js stuffs)
// We also need to set the method = replaceState always
// as this should not go into the history (That's how browsers work)
if (!this.urlIsNew(asPathname, asQuery)) {
method = 'replaceState'
}
```
the parameter here is `asPathname` destructured from `asPath`
so here is a problem when we reuse a single page rendered in two asPaths
pages/a.js
```
<>
<Link href='/a'><a>goto a</a></Link>
<Link href='/a' as='/b'><a>goto b</a></Link>
</>
```
If we navigate to page /a, then click 'goto b', actually the history is replaced, not pushed.
It is expected that history could be correctly pushed and popped as long as the browser url is changed.
