Do you guys have "Two-stage boot release"?

[TropicZ]

Do we have a 2-stage boot release on our cars? I have noticed that on some occassions when I press the boot release button, it unlocks with one press of the button and I can lift the hatch immediately. Other times, I find that the first press of the button unlocks it and I can hear the unlocking sound and it pops up ever so slightly but it is still latched and cannot be lifted. I have to press the button a second time for it to unlock and lift. Its almost like how the bonnet pops when you pull the lever but its still latched until you release it with the lever in the nose. Is this something to do with the intelligent key? Perhaps a safety feature to make it difficult for someone to nick something out of your hatch if the car was locked by remote?
