After resetting iPhone, does Find My iPhone remain activated?
In iOS 7, Apple introduced a new feature called Activation Lock. 

Activation Lock prevents someone from stealing your phone because they can't restore it and use it without your Apple ID and password. 

So yes, Find My iPhone is still on because activation lock is still on. Find my iPhone can only be turned off by going to settings > iCloud > Find My iPhone, then flipping the switch and entering your Apple ID password. 

You should need your password to activate the iPhone.
