LTM4700 RUNP PIN

Dear Sir 

My customer need to design in LTM4700 

This DC2702A-A EV Kit circuit RUNP PIN is connect to VDD33 PIN 

The customer needs to know why the SPEC reference circuit is not connected to VDD33, but the EV KIT User guide connects the RUNP PIN to VDD33

What is the difference between these two connections?
