Understanding Ford GEM Wake Up Diagram

I'm not understanding this quite right and would like a little help understanding how wiring this relay is going to wake up the GEM on my Ford F250.  My understanding of this relay's purpose was to pulse the door ajar wire to "fool" the vehicle into sensing that the driver door had been opened.  This relay does not seem to do that.  All this relay appears to do is break continuity on the door ajar circuit when pushing the alarm unlock button.   Would it not make sense to plug the RED wire in the diagram into 30, the BLUE wire into 87A and then run the YELLOW wire to 12V constant?  At rest, connectivity on the door ajar circuit will be unbroken for normal driver door sensing.  But when you push the alarm unlock button, that would send 12V momentarily to the GEM module.  How am I doing?  Certainly the smart guys at DEI wouldn't come up with a diagram like this if it would not do the job. 

check to be sure your vehicles GEM shuts down.  roll the drivers window down, lock the doors with the factory remote...or lock button on the door.  shut the door if it's the latter. wait a few minutes..3-5.  reach inside the open window and press the unlock side of the door lock switch.  if the doors unlock, you're fine.  if they don't, you need to wake up the GEM.  make sure the door latch wire is being interrupted, you don't have to use the driver's door, any door latch will work.

Howie II is correct, the NEWER Ford vehicles work opposite then what we have seen in pin switch wiring for the past 30 years so that diagram IS breaking the circuit to wake up th GEM!!
