It's yet to be confirmed if it is in Galar, however, I do hope it is. As for simultaneous captures, that only happened during the 3rd and 5th trips. If Ash does catch something, it's possible that happens in the previous episode, but any information of that is yet to be revealed.
I'm more onto this scenario due to the fact that in the opening, I saw Falinks near a trainer (Blonde ponytail, red and white clothes). Idk if we've ever seen this trainer before. It's probably got a trainer tbh.
