Do they have a mistake in the following example from the docs?

From the Middleware page:

https://laravel.com/docs/9.x/middleware#middleware-parameters

They give example with a class called EnsureUserHasRole

Then they say:

Middleware parameters may be specified when defining the route by separating the middleware name and parameters with a :. Multiple parameters should be delimited by commas:

Route::put('/post/{id}', function ($id) {
    //
})->middleware('role:editor');

But shouldn't it be:

->middleware('EnsureUserHasRole:editor')
