This image is probably from when the Royal Sisters have their premonition about Tirek. No way they would actually be sent to Tartarus.

I mean, in A Canterlot Wedding, Cadence was just sent to the caves beneath the capital.

Princess Twilight Sparkle just had Celestia and Luna imprisoned next to the Tree of Harmony.

In both cases, they never were sent to another location that was outside Equestria.

So Tirek has to spare them due to still being underpowered, and the sovereigns remain hidden until Tirek is defeated by the Chest of Harmony.
