I think a lot of that episode is setting up for the future.

Also they didn't forget about them? Isn't that what Amy and Rory were doing before they ran back to the Doctor

Also, some speculation:
In "A Town Called Mercy", the Doctor mentions something about Rory leaving is cell phone charger in Henry the VII's suite, and here in this episode they actually go to Henry the VII. Something timey wimey is going on here.

A common theory is that some or all of the first 3 episodes happen after the Pond's final appearence. It's based on the mini-episode where he does turn up in their bedroom after they leave the show.
