I believe that if your EAD is filed before you AOS the EAD does expire when the I-94 expires. I know that is how it works for the K1, not 100% sure that is how it works for the K3.
You're actually correct. The EAD will expire when the I-94 expires. For a K1, the I-94 expires 90 days after arrival at port of entry. But, for a K3, the I-94 expires when the K3 visa expires (usually 2 years). So, it is ok to apply for an EAD while on a K3, especially for those who want to wait until it's closer to their 2nd anniversary before filing for AOS so that they won't have to file for removal of conditions. The EAD, after all, is cheaper than the I-751.
