I think Zelena set the portal to take the person who jumped through it to sometime arround their parents met. She wanted to prevent Cora from giving her up, right?

So what if that is what makes Emma and Hook (Emma being the one falling first and therefore the one whose parents' meeting they'd be going back to) travel to sometime arround the late "The Shepherd" flashbacks and the first ones from "Snow Falls".
