But there is *also* a vector of frequent physical travel that the author 
tales pains to display, so that resonance explanation need not be valid. 
It may just be another of Green's notions.

As for it being the only story with such a justification, I can think of 
at least three others: Lawrence Watt-Evans' _Out of This World_ and 
Christopher Stasheff's Greymarye series, where the present days in 
worlds of different histories are similar because the mental powers that 
bridge between the worlds only works between worlds where someone is 
thinking with a similar vocabulary along similar lines at either end. 
John M. Ford's _Fugue State_ and his metafictional work in GURPS TIME 
TRAVEL establishes that of all possible worlds, only the most similar 
are reachable with finite resources, and "similar" comes in various degrees.
