I have a theory about the mirror.

It seems that every creature in Equestria must have a strong connection with their counterparts in the human world. The reason the Sirens, Sunset Shimmer, and Twilight Sparkle was there is because their human counterparts are there. When they go through the portal, they enter the other world at a certain timeline because that's when their human selves existed, and at the exact age as they are now.

For example; Twilight was a filly when Sunset left Equestria, and Sunset is a full-grown mare. So if Twilight went through the portal then, she wouldn't arrive the same year as Sunset. Sunset would arrive there when Human Sunset is a teenager, and Twilight would've arrive there when Human Twilight is still a little girl.

That would explain the age differences between Twilight and Sunset, and how the Sirens were there after a thousand years in Equestria.
