Twilight Sparkle, along with her friends, family, the Cutie Mark Crusaders; minus Dinky, and her new Mobian friends end up back in the time where the Mobians ended up. But the ponies became Mobian versions of themselves. They would have to wait a while for the Time Machine plans to be finished, so they have to wait a while until the Time Machine is finished. If they might be in the past, Twilight might as well do some research while she's in the past.
