Watching the embed, it's clear that the "black dot' is just another jet in the distance, on the approach to the Mexico City Airport.
Because of the mountainous terrain, the approach routing isn't "straight in" as you usually expect.
It took some searching to find this online, and not copyrighted....sorry it's so small:
You can zoom in with your browser controls, I suppose. (Can anyone sharpen it up, to be able to read the writing??)
That is the Jeppesen Approach Plate for the Runway 5R DME-ILS to Mexico City (MMMX). (Jeppesen is the major supplier to many pilots, worldwide).
Runway 5R (Five Right) is the most commonly used arrival runway for Mexico City. The brown and tan portion to the West of the airport depicts the
terrain...in a topographical format.
You can see, in the "plan view", the course comes from the North, on a Southerly heading, and makes that very sharp left turn to join the final
approach.
Anyway, in the YouTube video, that is most likely what's seen....another jet on that Southerly course (called the "transition leg") as part of the
Approach Procedure.
BTW, that is a very challenging Procedure to fly properly --- requires good planning, early landing configuration, at just above your final approach
speed, in order to be able to fly that last left turn's tight radius, and not over-shoot.
