The pointer isn't really relevant to what I'm sharing. I'm talking about what it is logically, not how it might be represented physically. You could certainly make each commit contain the other one physically if you wanted to represent it that way in some programming language. Of course there's not much of a reason to, and it'd be annoying since they'd be different sizes, but it's not like your have infinite recursion or something preventing you from doing that. What I meant is something else though. A linked list is a linked sequence of nodes (or a chain of nodes, if you wish to call it that). A branch is a linked DAG of nodes, if you wish to call it that. Calling a branch a sequence of commits feels like calling your extended family (or I guess your genealogy) "a sequence of people" - it misses some crucial aspects of the structure and just sounds very confused.
