Laravel 8 Class Based Model Factories - laravel

Question

I'm trying to figure out why when I try and create a factory of my Player class and dd($this) it comes back as that its not overriding the state of the model. What also doesn't make sense is that it is a collection of two items for the states.
Can anyone give further clarification for any of this?
$player = Player::factory()->injured()->create();
<?php
namespace Database\Factories;
use App\Enums\PlayerStatus;
use App\Models\Player;
use Carbon\Carbon;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
class PlayerFactory extends Factory
{
/**
* The name of the factory's corresponding model.
*
* #var string
*/
protected string $modelClass = Player::class;
/**
* Define the model's default state.
*
* #return array
*/
public function definition(): array
{
return [
'name' => $this->faker->name,
'height' => $this->faker->numberBetween(60, 95),
'weight' => $this->faker->numberBetween(180, 500),
'hometown' => $this->faker->city.', '.$this->faker->state,
'status' => PlayerStatus::__default,
];
}
public function injured(): self
{
$this->state([
'status' => PlayerStatus::INJURED,
]);
dd($this);
$now = now();
$start = $now->copy()->subDays(2);
$this->hasEmployments(1, ['started_at' => $start]);
$this->hasInjuries(1, ['started_at' => $now]);
return $this;
}
}

The method call:
$this->state([
'status' => PlayerStatus::INJURED,
]);
does not modify the current object - it creates a new Factory Instance with the updated 'status'. And this new Factory should be returned by the injured method.
In this case one solution would be:
public function injured(): self
{
$injuredPlayer = $this->state([
'status' => PlayerStatus::INJURED,
]);
$now = now();
$start = $now->copy()->subDays(2);
$injuredPlayer->hasEmployments(1, ['started_at' => $start]);
$injuredPlayer->hasInjuries(1, ['started_at' => $now]);
return $injuredPlayer;
}
