authentication: SessionAuthenticator `'identify' => true` config does not work

What i did:

$authenticationService->setConfig('identityClass', User::class);
$authenticationService->loadAuthenticator('Authentication.Session', [
    'fields' => [IdentifierInterface::CREDENTIAL_USERNAME => 'email'],
    'identify' => true,
]);
$authenticationService->loadIdentifier('Authentication.Password', [
    'fields' => [
        IdentifierInterface::CREDENTIAL_USERNAME => 'email',
        IdentifierInterface::CREDENTIAL_PASSWORD => 'password',
    ],
    'passwordHasher' => 'Authentication.Default',
    'resolver' => [
        'className' => 'Authentication.Orm',
        'userModel' => UsersTable::class,
        'finder' => 'session',
    ],
]);

After logging in, i manually modified logged user database row and refreshed page and identity in session did not update.

After investigation i have determined that new and updated identity that was indeed fetched from database but this condition resolves to false and this new identity value is never written to session
