Frank,
What I mean to say is: Once the string is at the tuning post, wrap the string over the top of the post and point it toward the outside of the peghead perpendicular to the neck. Put four fingers adjacent to the tuning post on the side of the exiting string to measure the length to trim the string to. You're right - the curl thing sounds like an exercise machine owner's manual printed in Taiwan to English transcription of.
If this is too abstract, I'll have to take some pictures, cuz - Confucius say: A picture is worth a thousand words.
