My answer to your question is both yes and no. I only do one pass, and I do not concern myself with the whole WTG, XTG, ATG bouhaha. Instead, I follow a do what comes naturally approach. By this I mean that I shave each area of my face using strokes that feel right for the area. For example: I shave down both sides starting at the temple with the stroke curving toward my chin. This results in a more or less WTG stroke at the temple that changes to an ATG stroke across the jaw line. So some parts of my face do get the ATG treatment and some don't. Interestingly enough, I find no difference in shave quality from point to point.

This "Natural" approach has several advantages.

1) It produces the optimum scything action without effort (or even much thought).

2) It minimizes the chance of injury as the most common cause of serious cuts is from trying to force an unnatural motion on your body.

3) If follows naturally follows the contours of your face, minimizing irritation.
