1. in suffering with him -- so, she suffered alongside him -- His suffering and sacrifice is what saved us
2. She co-operated in the work -- so too do you co-operate with Christ when you pray and follow His gospel
3. you need to link "this saving function, " with the this referred which is "This motherhood of Mary in the economy of grace"
4. "but by her manifold intercession," contains the same significance as you interceeding with God for someone else, as in you praying to God for someone else
5. "she continues to win the gifts" -- note: She wins it. From whom? From God, from the Sole Mediator between sinful humanity and righteous God -- her Son, Our Lord and God, Jesus Christ.
Yes, I have heard the same vatican double speak for some time now. "She's a Mediatrix while Jesus is the sole Mediator; She's a co-redemptrix while Jesus is the only redeemer; All graces flow thru Mary and Jesus is the source of all grace."

The schema of the Dogmatic Constitution on the Principal Mysteries of the Faith, drafted for the First Vatican Council (1869-1870), includes the unique mediation of Jesus Christ as one of these principal mysteries: "Truly, therefore, Christ Jesus is mediator between God and man, one man dying for all; he made satisfaction to the divine justice for us, and he erased the handwriting that was against us. Despoiling principalities and powers, he brought us from our longstanding slavery into the freedom of sons."There is also quite a difference -- God is the only one who grants something, any saint can only pray for this and for us to be favored by God who alone can grant this
