Yes, but according to the leaderboard, I was the runner-up, ranked at the 2nd place.
My understanding is in the event of a score tie in multi-round tournament, the player submitting a better score in the latest round prevails. (And that's why I've got the winner's purse, I assume?)
I don't know whether this leaderboard error is a known issue or maybe it's just me who's never seen it before and didn't know, but I just wanted to post it so that WGT becomes aware of it in case they didn't.
