old H1b amendment got approved unitll 2018 after new H1b amendment got approved for 2019

Hello All,

I’m in H1B. I am working for same Employer but changed clients. I worked with client A till Aug 2016, My employer filed my amendment+ extension (since my H1b was also expiring )for client A in normal process on March 2016, But before the petition got approved my project ended (Aug 2016). So I started my new project with different client B within same city. I filed a new amendment + extension with client B in Premium process and Got it Approved in October for 2019(H1 expiry). Now my earlier amendment + extension also got approved in November for 2018(H1 expiry). since the latest approval is for the client A

  1. will this affect my H1b validity in any way?

  2. what would be my I94 expiry date (as from forums understood it will be latest approval)?
