This is correct, and a nice box of surprises when flying codeshares to guess what fare code it will match on the operating carrier.
The issue is that VS is not *A.
No clue about MP, but on M&M or DC no miles are earned if ticketed on a non-*A airline (that is not their partner) even if operating metal is *A.
The opposite sometimes does earn bonus miles on specific agreements.
