Australian Open 2020

There was really no momentum at that point, the umpire gave 2 time violations to break Novak's serve at 4-4. Thiem held serve to take the set.

Are we talking about the same event or a separate incident, Djokovic was trailing 2 sets to 1 when he called the medical timeout?

That was a whole set after he lost the 2nd set due to time and umpire contact violations.
