Having said that, there is more of a will in the FFXIV team to keep things consistant and lore-connected (FFXI was constantly contradicting it's own lore beyond the first expansion) so I would not be surprised if Mr Oda and Mr Koji-Fox come up with some clever means of explaining how we can still freely teleport between the First and the Source after the first time travelling without having to lose our ability to teleport normally.
I think it will be as easy as establishing some sort of connection between the crystal tower in Eorzea and the one on the First. Possibly to link their aetheryte networks and even potentially open a way for non echo having npcs to travel if they want a way for that to happen.
