They are the same in relation to the flex-direction. Justify goes with the direction, align goes perpendicular to it. But still I agree, I've now been using flexbox for a long time and I still find myself second guessing a lot.

Reading your comment gave me the mnemonic “a line goes perpendicular to it” which I think will come in handy (for me at least).
