boost::two_graphs_common_spanning_trees

Given Output is:

Iterate over iG_o
(0,1) (0,2) (0,3) (0,4) (1,2) (3,4) 
Iterate over vG_o
(1,2) (2,0) (2,3) (4,3) (0,3) (0,4) 
Reading trees
1 1 1 1 0 0 
1 1 1 0 0 1 
1 1 0 1 0 1 
1 0 1 1 1 0 
1 0 1 0 1 1

If we focus on 1st row that is 1 1 1 1 0 0 Then it means common spanning tree have (0,1) (0,2) (0,3) (0,4) edges but edge (0,1) is not present in the vG_o then how it would be in common spanning tree??
