 There are several versions of this strategy. Here’s one: Black remains inactive only because his device detects in Jones no inclination to vote for the Democrat. But then it looks as if Jones had an alternative after all: he could have been inclined to vote for the Democrat. This alternative would not have issued in a choice, but it is an alternative for all that. But this sort of flicker is not especially useful in defense of PAP. For one thing, it seems to locate the alternative at the wrong time, and regarding the wrong action (if indeed an inclination can be considered an action at all). For another, there may be FSCs in which Black does not rely on any such prior sign before the moment of choice  (§4.3.2).
