It applies to hand assembling electronics with through-hole resistors, also. Install them so the color code reads left-to-right in the most usual orientation of the board. Yes, it does not matter electrically which way you install them, but it makes it easier to read off values. Yes, I thought my boss from years ago who insisted I do it that way was crazy. Once you learn to notice it, though, resistors installed in inconsistent directions will bother you.
