Hi
If Leila brought her "vanilla identity" phone with the FB app in her purse while meeting her clients, I'm fairly certain FB tracks patterns of FB users meeting in the same area on a regular basis to suggest they know each other.
It can probably be confirmed by attending events where you do not normally go and where the same people go a few times and then checking if some of the faces you saw at these events start appearing in your friend suggestions list.
Like the others were saying: if you have multiple identities, don't use FB at all.
