Actually, although the outcome of the application of psychology in this episode was a bit dodgy, I still like how Raiga in the end disintegrated himself, just like DarthEnder said. Why not go with a flash, if you are a goner anyway...
I imagine it's because he had the reaction most people would have. That stuff is god-awful. Neji probably has a very refined pallette. Plus, it was funny, and it kept him out of the fight, so they couldn't make him look incompetant AGAIN.
