That's a widespread class of bug (deserving of a short, memorable handle like off-by-one, semantic collision perhaps?), but could it apply here? I'd sure hope that the world's most prominent authentication provider would keep their 2FA more isolated than that from their ad pipes.

It allows them to tie your instagram usage to your facebook account to your whatsapp conversations even if none of them are linked together, and then create a big map of all of the people you interact with on the different platforms. The more phone number information they have, the more powerful their map.
