Forgive me if I'm mishearing or misunderstanding, but at around 11:48, I though you said you want the x-axis of the shin bone pointing at the knee pole, so you rotate the bone until this is so. But then, as soon as you select it, it snaps so that the shin's x-axis is pointing along the global Y and the knee pole's x-axis pointing along the global Z. Am I mishearing? Or can you break down a little more what is happening here?

Thanks. I'm enjoying the course!
