If the saying is about sticking, wouldn't "pursue what departs" mean to stick and follow?

If you stick and follow with one limb, you must use the other to strike. Then you no longer have the lin siu daai da function with one limb.

if you strike with a straight punch and I intercept your strike with a straight punch of my own, but I have/create a better angle and so my punch gets to its target as it deflects your own punch. In that example, there is still contact as the line of attack is cleared - or maybe it is better to say a new line of attack is created).
If a car speeds through an intersection and sideswipes another car we wouldn't say it was sticking to it. There is no sticking taking place there, just a collision that happens if the timing is right because of the intersecting paths.
