I'd really like to know how these two people from different parts of the globe came to collaborate with each other. I know we live in the age of Internet and all but I'd really like to know how such people find each other and collaborate.

I missed out on this kind of collaboration when I was in college. But learning the answer to this question might be helpful to others who might want to do such collaboration but do not know how to get started.

Know each other's work through publications, connect via email (ostensibly to ask for clarification on a detail, or to request a preprint), maybe meet at conferences but not always. I've written a couple of papers with people who I've never met in person (and that's not uncommon).

We were graduate students together sharing an office, and have been friends since.

One of them might have been at the other's institution for a period before moving back or on. That's quite common in academia.
