I suspect everything is working just as designed. Some Nissans and Infinitis have the upper vent feature. You can disable it in the climate settings.
If you'd like to see a demo of it in the M, check out this video -

While the 2011+ specific section starts past halfway into the video, you might find it beneficial to watch the whole thing.
Something I'd like to say, is that I've heard of some people complain of the 2 condensation spots. I played around in the system to try and replicate it, and I found that:
1. They should disappear/dissipate rather quickly once you start the car and have the system running on AUTO
2. They are more likely to appear if the driver tweaks the AC system during normal operation (fiddling with the fan speed, mode or recirculation buttons). The system works best when left in AUTO.
