I don't think you understand the page cycle here.

rainlab.user.register is called after the user has already been registered. I.e. they have already passed validation and already exist with the invalid username.

What you can do instead is bind to the User model's model.beforeSave event and do your own validation of the username:

public function boot() {

    \RainLab\User\Models\User::extend(function($model) {

        $model->bindEvent('model.beforeSave', function() use ($model) {
            $validator = \Validator::make($model->attributes, [
                'username' => 'required|alpha_dash|between:2,50',
            ]);

            if ($validator->fails()) {
                throw new \ValidationException([
                    'username' => 'Username must contain alphanumeric values only, and be between 2 and 50 characters in length',
                ]);
            }
        });

    });

}
