Yes (but that's also the case in version 1).

Here is an example:

Point(1) = {0,0,0,0.01};
Point(2) = {0.1,0,0,0.01};
Point(3) = {0.1,0.3,0,0.01};
Point(4) = {0,0.3,0,0.01};
Line(1) = {1,2};
Line(2) = {3,2};
Line(3) = {3,4};
Line(4) = {4,1};
Line Loop(5) = {4,1,-2,3};
Plane Surface(6) = {5};
Recombine Surface{6} = 80;

Best,

Christophe
