10 yr multiple entry expiring, but date on I-94 given until a month later

My Inlaws are on a 10 yr multiple entry visa. 10 yr entry visa on passport ends on sep 9th 2017. But when they came to US this time on April 22nd. They gave the I-94 until October 10th. Would they be able to stay until October 10th as I-94 is valid. Thx

Visa lets them enter. I94 lets them stay. Yes, They can stay.
