This strikes me as a decent benefit to Instagram. Otherwise, why would they leave sessions active after password resets? That's standard practice for any large service. Now, not only do you know the habits of individuals, but now you have insight into their closest friend networks and I bet can glean a more information from that fact. I'm sure this technique doesn't anonymize the people in the group, because I bet they aren't all using burner phones for insta. However, it does make it difficult for external data brokers to get that information, so maybe there's a sales opportunity in here.
