Thanks for the response. As I suspected, there's less than meets the eye. It's pretty amusing that they used land-based aircraft for the pics rather than simply acknowledge that they did not have an operational carrier squadron.
They have also practised and trained with three of their pre production models which are carrier qualified. They have trained one group of eight pilots with those aircraft already, who are now training more.
Here's a couple of pics of them training/qualifying off of the Liaoning earlier this year.
Here's a link to an earlier video of the same:
