Of course he would.
There is just one thing that threatens Djokovic on hardcourts, and that's speed. Medvedev's game is simply too slow to threaten Djokovic on this surface. Tsitsipas on the other hand has much more pace.
This is a really matter of a draw.
Of all players in bottom half Tsitsipas is the worst matchup for Djokovic, easily. But chances of Tsitsipas getting through two very bad matchups of his own in Nadal and Medvedev were not great. Medvedev has always been odds on to make finals from bottom half, and that made Djokovic's chances even greater. Drawing a meekly Zverev and Karatsev and having an extra day of rest just sealed it.
