Why can SSO1 obtain user information normally, but SSO2 still needs to log in?

[IceCry]

Version: v0.4.2

I have created three websites:
Server: sso.xxx.com
Broker1: sso1. xxx.com
Broker2: sso2.xxx.com

The configuration is as follows:

'brokers' => [
    'sso1' => [
        'secret' => 'secrethelloworld',
        'domains' => ['sso1.xxx.com'],
    ],
    'sso2' => [
        'secret' => '7pypoox2pc',
        'domains' => ['sso2.xxx.com'],
    ]
],

When accessing SSO2, userInfo can be obtained normally. When accessing SSO1 again, I think that $userInfo=$broker ->request ('GET ','/api/info. php ') can directly obtain userInfo information, but in reality, it was not obtained, What is the reason for this?

Please share your information for me. Thank you. @jasny

访问sso2时可正常获取userInfo，再对sso1进行访问时，我认为通过$userInfo = $broker->request('GET', '/api/info.php');可以直接获取userInfo信息，但实际上却没有获取到，请问这是什么原因导致的呢？

why they get the diffrent session
