Pitying fools as hard as I can...
You are correct. It's worth noting, however, that the current ruling is that while she can technically also trigger the ring effect when winning a conflict on defense, doing so (in the vast majority of cases) would only benefit the attacker.
Ah, because the Ring effects specify "the attacking player" and Doji does not say "as if you were the attacking player" as I saw some other cards that mess with Ring effects do. Thanks for pointing that out.
