You point it out as the prerequisite, but having both people on the same page as to how to play the interruption game is I think non trivial.

In particular, people not used to get interrupted don't structure their talk in the same ways, and that makes is difficult to ad-hoc switch from one style to the other.

IMO talking in small bursts and checking on the listener to see how they receive it could be seen as the best of both worlds and work with less coordination than either style.
