HEAD and the branch have separate reflogs. Each step of an interactive rebase adds a separate entry to HEAD's reflog, but the branch's reflog only ever gets a single new entry when the rebase is complete. So you can run e.g. `git log -g master` and skip the rebase intermediate steps.

It is rather unfortunate that there is no convenient documented shorthand for "show me the reflog of the current branch" (`git log -g` gives you HEAD's reflog). That said, after a bunch of experimentation, it seems like `git log -g '@{0}'` will give you the reflog for the current branch. Apparently this works because e.g. `git log -g '@{2}'` gives you the reflog for the current branch skipping the first 2 elements.
