The tailgate button on my remote opens up the automatic tailgate but if I want to unlock it so I can manually open the tailgate, I would need to do as you say and press the door unlock button twice. Interesting, I am guessing that the tailgate button has no function if your tailgate is not automatic. You're right, it would have been smart to make it at least unlock just the tailgate, but it looks like the tailgate lock is connected to all the door locks.
