In this specific case? very likely. In general? It's not clear what exactly causes one to repel the light of IT. If sasuke possessed whatever ability BZ has to block the light (and without rinnegan), his susanoo would still block the light.

Either way it's a clear death of the idea that 1: the rinnegan is immune to Genjutsu (as this is based upon it blocking IT) and 2: only the rinnegan can block it (simply not true)
