The option activates the automatic duplicate entity removal that is 
performed every time a geometric transformation (translation, extrusion, 
etc.) is used.

You can force the duplicate entity removal "by hand" (even if there are 
no geometrical transformations) by adding "Coherence;" in your script. 
For example:

Point(1) = {0,0,0};
Point(2) = {1,0,0};
Point(3) = {1,0,0};
Line(1) = {1,2};
Line(2) = {1,3};
Coherence;
