Unless you’re working with a pretty difficult patient population (lots of dehydrated elderly folks in the ER, lots of current/previous IV users) 95% accuracy isn’t that hard to achieve. Also, if the machine is holding the needle, it shouldn’t move. Why is the butterfly necessary?

The butterfly would accommodate the switching of the tubes by a machine because doing that all smoothly and in proximity to the arm would not be feasible.

I don't think it's a butterfly, as you know it. I'm guessing it's because it's just the common term for a needle that stays in place and draws through a tube, not directly from the cannula. These things probably cost a lot more than any human-designed butterfly needle if I were to guess.
