Why Paralleling Multiple LT3045s PGFB not tied together?

Question

Accepted Answer

Question: Why are the PGFB (Powergood Feedback) pins not tied together when parallel configuration is used based on the datasheet sample circuit page 27? 
 Answer: All the SETs are tied together so the regulators will act exactly the same. Since one of the LT3045 monitors the output voltage using its PGFB pin, it will provide ~2mA into the SET network until the output voltage is around 3V and then the ~2mA will reduce to 100uA like the rest of the LT3045 s. When the 2mA is on, the output voltage ramps up faster compared to when all the LT3045s contribute only 100uA.
