They probably have no ways of _knowing_ that. They might assume. But Nintendo also has absolutely no incentive to care if it's used for pirating. Users want to put in term of morality, when it probably doesn't matter much. Even if there was no pirating angle, emulation is a revenue drain from old title they could bundle in the Nintendo Online subscription and remix as remake games (what we saw with the old Zelda games remade for the Switch for instance). Even if people were using the emulator after buying the Switch and the actual games, that's still a stream they don't control (can't check if the game is played on multiple consoles for instance, etc) and there's nothing positive for them coming out of it.
