Direction of buffing a pipe?

When using a buffing machine, does it matter which way you present the pipe? That is, is there any difference between feeding the pipe vertically or horizontally (like eating corn on the cob)?

It's best to buff both ways (if possible). If you go in only one direction, you may leave noticeable lines if you look closely (like brushed metal). If you alternate, it will help get rid of this.
