I think this is normal. I have noticed that my Z does this too. I always put my bag and cooler in the hatch before leaving for work in the morning then I walk to the door and get in. The indication goes away after I get in the car or press the lock button. I'm guessing that when you open the hatch and are standing directly behind it, the key signal is strong enough that the car could be started, and as soon as you close the hatch and/or walk away, the signal is lost or fades and the car thinks the key battery is low.
