Ok, to be precise, a domino effect would be the same every time, you set it back up and they get knocked down the same.

Water flowing over the ground is subject to Chaos Effect (we’re not talking about you, Discord!). When the water is diverted, it's flow will be affected by imperfections on the ground, air currents and physical barriers. But if you remove what diverted it in the first place and then replaced it, the flow isn’t going to follow the same path because you can never EXACTLY replace the diversion.

So even with Twilight's correction of Starlight’s interference, the time flow has been altered. The ‘now’ that Twilight and Co. are living is not the same ‘now’ if Starlight had never acted on it.
