It's rather odd for that to happen in an Uzbeki Challenger though. It'd be more likely in South American events or even European Challengers, where such WCs are more common.
For sure it's odd.
Anyways it should be good experience for him to play against the 1st seed. He doesn't stand many chances as it's against Kavcic on a clay court, but he will take some lessons from that. He is doing things right in his career, Larri Passos seems to be making the right moves.
Good luck to Tiago, Axel (glad he qualified) and Laurynas.
