Comment (by strk):

 For the record, the distances of those two internal vertices of Edge2 from
 Edge1 are:
 {{{
 =# select n, ST_Distance(e1.geom, ST_PointN(e2.geom, n))
    from t5862.edge e1, t5862.edge e2, generate_series(2,3) n
    where e1.edge_id = 1 and e2.edge_id = 2;
  n |      st_distance
 ---+------------------------
  2 |  4.855711461806118e-16
  3 | 2.8243441995579915e-15
