I still haven't figured out how the undo-direction works in emacs. It feels like half the time I'd inadvertently end up redoing.

it treats the undos as new changes to the buffer, and adds ;; them to the history:

If you did an undo in the history, it will look like a redo. So if you just did a bunch of undos, it will feel like redoing, but you are actually removing changes made by your undo.
