I think this scene does add something, which is showing how scary this environment is to droids as R2 and C3pO are walking in. It shows it quickly, efficiently, without having to use dialogue on it. It takes ~15 seconds, and also has the fun side-effect of being a cute easter egg to anyone who went to star tours.
I think it's a rare example of a good easter egg because it still communicates something important to the scene without just feeling like it's there for a nod or reference.

I don't think that was an explicit callout to Star Tours -- which opened at Disneyland years after RotJ came out (1983 and 1987). If anything, the easter egg went the opposite direction!
