I also think it's Iberian...
But that clip is definitely incredible.
I've got some other situations that look like that, it's always very impressive.
I've noticed that the hold short instructions are unkown to many foreign carriers. For example, at Montreal, when controllers ask to Air France to hold short, the french way to say it, they can't understand. Same thing for carriers like Cubana, CSA, etc (KLM and British are not included). Controllers end up to say "hold position" or "line-up" instead of "taxi into position".
