This is a common misconception and it stems from a different process. The chemical reaction that causes the pink smoke ring formation due to formation of nitric oxide in the outside quarter inch or so of the meat will cease above an internal temperature of 140F. For this reason those seeking larger smoke rings will put meat on the smoker directly from the refrigerator. As an aside, the chemical reaction causing the meat to become pink due to smoke exposure is the same as that causing cured meats like bacon or salami to become red when treated with sodium nitrite or nitrate. In this way one can "fake" a smoke ring by using pink salt or sodium nitrite as a rub element - and KCBS BBQ judges are instructed to disregard the smoke ring for this reason.
However, the application of smoke flavor onto the surface of the meat, and not "into" the meat as devilbliss writes above, will continue so long as smoke particulates are present in the cooking environment.
In a hot smoking environment, the surface of the meat quickly dries out, and the volatile smoke molecules that cause smoke flavor will adsorb (stick to), and not absorb (penetrate) into the meat. This process will continue for however long the meat is exposed to smoke, even if smoke ring formation has long since ceased. If you want to test this, try cooking two identical pieces of pork shoulder or brisket - take one off the smoker after four hours and place it in the oven at the same temperature until both are done. See if the one you left on the smoker tastes smokier (or maybe, too smoky?).
In a cold smoking environment smoke flavor can penetrate throughout a piece of food, as the surface never dries out from heat and smoke is both absorbed and adsorbed.
