In any event, at 180 the authors also say this, they say
"... if all visible targets are completely superimposed, using our system of standards, it can be considered a positive identification."
That is the 58, they say if they are completely superimposed, then it is positive. 
"... on the other hand, a match is ruled out if two or more targets cannot be superimposed."
and then it says ...
"... finally, when only one target does not fit, the possibility of identification exists."
So coming back to the categories, he says if there is one that does not fit, it is still a possible, when two don't fit, it is out.
Would you go along with that in principle?
