This is not what strict means.

DMARC for a domain in header "From:" requires matching DKIM dignature from 
that domain OR matching SPF from that domain. One of them is enough.

You misunderstand what "strict" means. It's related to subdomains.

From: [email protected] in "strict" more requires DKIM or SPF for 
"sub.example.com", in "relaxed" mode DKIM or SPF from "example.com" is 
enough.

Neither policy requires matching both SPF and DKIM

Benny if you have info supporting your theory please point us there.
