Nice discussion on tri footwork. Wing Chun has a similar method, found in the dummy form.
Moving from a bong chor sau (bong sau to the inside of an opponent's bridge - we call this Wrong Bong ), and moving bong to tan sau with a palm strike to the ribs.
This hand method is accompanied with footwork as per your description. A kinda out-and-then-in motion in one fluid move.
With regards moving the head out of range against the jab, we tend to do this also with a subtle shift in footwork while raising an arm to bridge (make contact) with the jab. As soon as the jab retracts, we follow. (Receive what come, "escort what leaves", on loss of contact... strike)
Recently we've been working on a series of sensitivity drills that deal with this: adjusting to avoid an attack, bridging, following the retracting hand (which more often than not opens up an attacking angle).
The drills involve using a flexible tan, bong or pak sau, and issuing with an appropriate hand attack.
