When multiple people launch this feature in close proximity, they'll see each other's names in a list, even if they're not friends on Facebook. For each list entry, there's a button to quickly add that person as a friend.
To be clear, the feature only works when both parties have the Friends Near Me page open at the same time. In that sense, it's a lot different from the infamous "Girls Around Me" app, because it doesn't draw on public data, and only locates people who are actively looking for other Facebook users.
