Butterfly picot bind off

I am making a capelet and would like to do the picot bind off. The instructions tell me to CO 2 stitches and bind off 4 stitches. I can Not figure this out. It is probably very simple but it has me stumped. I think I have seen this bind off using the butterfly picot bind off. Can anyone help me with this problem.

Okay, so I think what happens is this: You cast on two. These will end up on the left needle. Just treat them as regular stitches to bind off. So the next four you bind off will be the two you just cast on, and then the next two, which were there from before. The new cast on stitches will get bunched up between the regular bind off stitches and make your picot bumps.
