Yes, the test was on performance in dogfights, not BVR interception performance. Rate of turn etc. I think the harrier has the edge, especially where it can vector its thrust, even if not in speed (by a long way - it is afterall subsonic).
That being said, I would've thought a harrier would avoid BVR engagement by closing range at v. low altitute.
