Jeff,
In this particular case, that bracing isn't doing much good because the rafter is incorrectly spliced. The brace is on the half that has the 2 foot or greater scab. That leaves the lower, incorrectly scabbed section unsupported unless there is a correctly sizd Purlin very near it. Regardless, the scabs are not correct. I say SE time and you have done your job.
