Schulze is a Condorcet method, so that it wants to elect the candidate who could defeat any other candidate head-to-head.

When such a candidate doesn't exist, then Schulze wants to find the candidate whose worst loss is the least. (The idea is to reduce the number of voters who have good reason to object to the outcome.)

But simply doing this would violate clone independence. So beatpaths are used to ensure that a candidate doesn't lose simply due to being a clone.

That's not very formal but it's how I would explain it.
