Question about "or" statements

In this question, I created a chain combining relevant rules: (F or V) -> not T->not M->not R->L. I understand that V being present is sufficient to know that T, M, and R are all not in. But if F and V are in, would it still activate the same chain of rules depicted above? Generally speaking, if you have both variables in an "or" statement in the sufficient condition, such as F or V in this example, would having both present still guarantee the necessary condition of not T?
