The iPhone has a few mics in it. When away from one's head, speakerphone is engaged and the omnidirectional mic is active. When next to one's head, the mic becomes unidirectional. So, when the person rotates the iPhone so the mic faces up, it only picks up sounds which are above the persons head. As the iPhone is also utilising active noise cancellation technologies, most quieter sounds from above the person are filtered out. In other words, it is not actually muting the mic, it is directing the mic toward an area where the sounds are not usually very strong, so they generally get filtered out. If one actually wishes to ute the mic, I would not trust this method to do the job consistently. However, for a quick and dirty simulation of mute, it is adequate.
