That just freezes the world during the path following. Which I would consider a bug - in the Etoys image, path following happens simultaneously with all other animations.
Adding such a delay would be trivial, just have a textual script with something like "(Delay forSeconds: 1) wait". But that would not be a substitute for a real "wait" tile. It does not just stop the script it is in, but *every* script in the whole system.
