What C-C Fallacy? 6

Then a bit later in "The Extended Mind," Clark and Chalmers write,
In these cases [of different modes of Tetris play, use of pencil and paper, etc.], the human organism is linked with an external entity in a two-way interaction, creating a coupled system that can be seen as a cognitive system in its own right.  All the components in the system play an active causal role, and they jointly govern behavior in the same sort of way that cognition usually does.  (Clark & Chalmers, 1998, p. 8)
The first sentence indicates that a two-way (causal?) interaction between a person’s mind and certain environmental items, such as a video screen, pencil, and paper and so forth creates a coupled system.  Clark and Chalmers, however, apparently take the existence of extended cognitive systems to be sufficient to establish that cognitive processes extend.   The second sentence backs off of this a bit, noting both that all the components in the system play an active causal role and that there is some kind of cognitive equivalence.
