It could be hard if you never took Discrete or another course that introduces graph theory. Or if you cheated your way through or barely scraped by. I can see how a CS freshman or someone from another field might struggle, but even then it's more comprehensible than any of the alternatives.

Even that is only true if you're coming from a system where branch, tag, and checkout mean something else.
