It's potion time!
REGARDLESS!He doesn't, some of it is inspired by Go but he isn't one to one following its mechanics lmao. He still battled to catch Pokémon and uses ball throwing techniques u can't in the game.
His name, his dex, and his penchant to throw a ball without doing much fighting indicates he's way too into Pokemon GO mechanics.
Whenever he has to battle, that's just because the universe suddenly forces him to abide by the usual rules...although, if I recall, Raid Battles are from Pokemon GO too.
