The first 49 Moves you see in the clip were actual moves from a game, played in 1991, between Anatoly Karpov (White) and Garry Kasparov (Black), albeit, at this stage, they were between Moves 62 to 112! ...
Their game was a proper epic, which actually took in a whopping 115 Moves ... and, appropriate for this topic, ended in a Draw.
While they chose not to end it by completing the 50 Move Rule, for this example, I've added what might have been made, to implement that Rule.
This long, drawn out, 50 Move saga probably explains why Stalemate by the Three-time Repetition Rule was devised: you still get a Draw - a Stalemate - but you now have time to nip to the vending machine for another coffee.
