Those aren't words of wizdom - that's just how you keep from busting your chin and killing yourself on a jerk. Shoulders come forward, elbows are down and head is back a bit. This allows the bar to clear the head. As the bar clears your head you drive your head forward between your arms which really serves to recruit the back for stabalization and increased power.
Let me tell you, there is nothing in the world like getting ready to jerk heavy weight, sending that bar screaming up, and having it blast through your chin and head, and then obviously come back down on you. It's like taking a massive metal uppercut on the chin. Plus it makes you look like a moron and it takes some time for you to recover enough to laugh at yourself.
