That't not what the code is saying, the magic is clear in the else branch. If SingleFixMode is enabled we are only querying the set, If its disabled then we are updating the set. 
The real shortfall is the map is called InsertedHeaders which is not a good reflection of what it actually contains. It actually contains all the headers included in each file. Which in `Multi` fix mode gets updated with each include insertion.
