Sounds like you left the car on.
Just for kicks, I left the car powered on (in READY mode which is the green car w/arrows). Right when I close the driver's door (w/o pressing any fob buttons), I get 3 beeps. Why? To tell me I left the car on.

Did you receive any confirmation beeps?
If there were none and you heard the door locking mechanism work, you either left the car on (see above) or you left a door or hatch open. I confirmed both of these.
I've run into the left a door/hatch open issue when I 1st got my Leaf and was puzzled. This behavior is unlike Toyota's where IIRC, you get a VERY LONG beeeeeeeeep in protest.

That's probably due to a by design feature where if you unlock the doors and no door is opened after a certain timeout, the car automatically locks itself. It's for cases where you forgot you unlocked the doors or accidental button presses. Toyota's w/Smart Key System (Toyota parlance) does this, as does my mom's 07 Altima Hybrid that also has a very similar Intelligent Key System as the Leaf.
Why do you bother screwing w/the key fob buttons in the first place? I almost never use any of the buttons, except maybe the charging door release (new feature on model year '13+ Leafs). I sometimes (but rarely) use the lock button from a distance to confirm the doors are locked (lights flash and there's a brief honk).
