Comment(by strk):

 The SQL query is in the ST_ModEdgeSplit function (and similar one appears
 in ST_NewEdgeSplit). This means the penalty only occurs on edge splitting,
 which should only happen when adding an edge which intersects an existing
 one.

 Hint for testing: use ST_ModEdgeSplit and ST_ModEdgeHeal iteratively while
 changing query/indexes.
