FrogReaver is not expressing a concern about the medium of interaction: the concern is about the way mechanical states of affairs (eg position, hit point tallies, etc, all established on a turn-by-turn basis) form a basis for action declaration and for action resolution, although the fiction that follows from those mechanical states of affairs isn't yet known.
And fiction is not resolved sufficiently because of an insistence that the fiction reflect simultaneous action, when the mechanic does not enforce this.
