There IS a branch at that point downrange, it just does not extend out that far (see the end of the replay where the "branch noise" occurs and the ball drops straight down - the branch is well into the left rough
I got out my WGT binoculars (Pro Shop - 10,000 credits) and saw that branch wayyyyy off the fairway. There was little birdie that flew off that branch, on it's way to the green, and BOOM!
I have gotten a few of those hard-to-see "birdies", myself!
Maybe WGT greenskeepers have found it.
