Luke hadn't explained it quite like that, but Anakin realized perhaps he should have drawn that conclusion.

He wasn't quite sure what to say anymore about that.

"Well, we can't leave until that glowing orb sends us back. We tried to leave but that... didn't go as planned." That was putting it charitably.

"Someone else said that the Orakalla will send us back to the moment it took us from. So there's a chance we can fix whatever went wrong back home."
