I think that's right. My hair is coarse and grows really flat against my neck, so my razors tend to hook under the hair and dig in on the ATG pass. This might be less of an issue for other guys.

Also, it's good to remember that you're aiming for beard reduction, not elimination, with each pass. If you go for broke on the WTG pass, you'll probably use too much pressure and irritate your skin.
