Indeed, it's a problem, but crossing string boundaries makes the behavior less deterministic. I agree it can be useful, but I'm not convinced it's worth the unpredictability: up-list can end up moving to some very far away string, that's completely unrelated. Currently noone complains because when the cross-string jump is not useful, it's not really worse than getting an error, but when the user intended to get out of the current string, she'll be very disappointed.
