I guess that's true since we also saw a talking Lapras here which didn't make much sense either, although I assumed that the North Pole location that was shown here was an anime exclusive place cuz I doubt Ash's group actually visited the Arctic.
It was an anime-exclusive locale since it wouldn't have made much sense for Satoshi's group to travel thousands of miles. As for Laplace, it wasn't explained how she knew human language, but it wasn't too unrealistic since Nyasu speaks as well.
