Why doesn't filling the model through model load work in Yii2?

Question

Yii

<?php

namespace common\models;

use Yii;

class MyModel extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'mymodel';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['name'], 'required'],
            [['name'], 'string', 'max' => 70],
            [['name'], 'unique'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'id' => 'ID',
            'name' => 'Name',
        ];
    }
}

$model = new MyModel();
var_dump( $model->load( [ 'name' => 'Vasia' ] ) );

As a result, var_dump will display false... Well, of course, the model will not be filled. Why might the model fail to fill?
