You can counter a wild draw 4 by also playing one, in which case the next player has to draw 8 cards. So if the POV character is to move, Osaka having a wild draw 4 for would turn what’s a sure victory for the POV character into certain defeat.
(Of course, I can’t actually know what Osaka has on her hand. I just figured her having a wild draw 4 would be funny in this situation)
