[GAMEPLAY] Neeko Audio/Visual Bug video

Hello guys, so me and my friends we were practicing Neeko in custom and we were disguising as our allies (which were bots). During my friend who disguises as his ally (rammus), then we suddenly heard Rammus's spinning ability's sound effect (the spinning sound effect) but he did not spin.

The same happend when my ally (Master Yi) were recalling, and I disguised the moment he initiated/ or almost the moment he initiated the recalling, then I had the recalling effect coming from me (NOTE: I did not recall, but the one I disguised as were recalling).

Sometimes you can also get the visual effect (If you watch the video, then you can see how my friend had the small glow effect/trail behind him while disguising as Rammus under his spinning ability. The same glow effect is behind Rammus when he spins around).

Neither me or my friend are sure if this is intentional or not... or if anyone has encountered anything similiar. I also hope what I wrote/ or what I am trying to present makes sense.
